VAR-200711-0560

Vulnerability from variot - Updated: 2025-12-22 22:31

Perl-Compatible Regular Expression (PCRE) library before 7.3 backtracks too far when matching certain input bytes against some regex patterns in non-UTF-8 mode, which allows context-dependent attackers to obtain sensitive information or cause a denial of service (crash), as demonstrated by the "\X?\d" and "\P{L}?\d" patterns. Perl-Compatible Regular Expression (PCRE) The library contains UTF-8 When processing regular expression strings in modes other than, important information is leaked or service operation is interrupted because it is read in excess from the beginning. (DoS) There is a vulnerability that becomes a condition.“\X?\d” and “\P{L}?\d” Format regular expression UTF-8 When used in other modes, important information is taken or service operation is interrupted (DoS) There is a possibility of being put into a state. PCRE regular-expression library is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code, cause denial-of-service conditions, or launch other attacks in the context of the application using the affected library. PCRE (Perl Compatible Regular Expressions) is an open source regular expression library written in C language developed by software developer Philip Hazel. There is an information leakage vulnerability in pcre's method of processing certain malformed regular expressions. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

Package : pcre3 Vulnerability : several Problem type : local (remote) Debian-specific: no CVE Ids : CVE-2007-1659 CVE-2007-1660 CVE-2007-1661 CVE-2007-1662 CVE-2007-4766 CVE-2007-4767 CVE-2007-4768

Tavis Ormandy of the Google Security Team has discovered several security issues in PCRE, the Perl-Compatible Regular Expression library, which potentially allow attackers to execute arbitrary code by compiling specially crafted regular expressions.

Version 7.0 of the PCRE library featured a major rewrite of the regular expression compiler, and it was deemed infeasible to backport the security fixes in version 7.3 to the versions in Debian's stable and oldstable distributions (6.7 and 4.5, respectively). Therefore, this update contains version 7.3, with special patches to improve the compatibility with the older versions. As a result, extra care is necessary when applying this update.

The Common Vulnerabilities and Exposures project identifies the following problems:

CVE-2007-1659

Unmatched \Q\E sequences with orphan \E codes can cause the compiled
regex to become desynchronized, resulting in corrupt bytecode that may
result in multiple exploitable conditions.

CVE-2007-1660

Multiple forms of character class had their sizes miscalculated on
initial passes, resulting in too little memory being allocated.

CVE-2007-1661

Multiple patterns of the form  \X?\d or \P{L}?\d in non-UTF-8 mode
could backtrack before the start of the string, possibly leaking
information from the address space, or causing a crash by reading out
of bounds.

CVE-2007-1662

A number of routines can be fooled into reading past the end of an
string looking for unmatched parentheses or brackets, resulting in a
denial of service.

CVE-2007-4766

Multiple integer overflows in the processing of escape sequences could
result in heap overflows or out of bounds reads/writes.

CVE-2007-4767

Multiple infinite loops and heap overflows were disovered in the
handling of \P and \P{x} sequences, where the length of these
non-standard operations was mishandled.

CVE-2007-4768

Character classes containing a lone unicode sequence were incorrectly
optimised, resulting in a heap overflow.

For the stable distribution (etch), these problems have been fixed in version 6.7+7.4-2.

For the old stable distribution (sarge), these problems have been fixed in version 4.5+7.4-1.

For the unstable distribution (sid), these problems have been fixed in version 7.3-1.

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS Ubuntu 6.10 Ubuntu 7.04 Ubuntu 7.10

This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the following package versions:

Ubuntu 6.06 LTS: libpcre3 7.4-0ubuntu0.6.06.1 libpcrecpp0 7.4-0ubuntu0.6.06.1

Ubuntu 6.10: libpcre3 7.4-0ubuntu0.6.10.1 libpcrecpp0 7.4-0ubuntu0.6.10.1

Ubuntu 7.04: libpcre3 7.4-0ubuntu0.7.04.1 libpcrecpp0 7.4-0ubuntu0.7.04.1

Ubuntu 7.10: libpcre3 7.4-0ubuntu0.7.10.1 libpcrecpp0 7.4-0ubuntu0.7.10.1

After a standard system upgrade you need to reboot your computer to effect the necessary changes.

Due to the large internal code changes needed to solve outstanding flaws, it was not possible to backport all the upstream security fixes to the earlier released versions.

Details follow:

Tavis Ormandy and Will Drewry discovered multiple flaws in the regular expression handling of PCRE. He reported an error when processing "\Q\E" sequences with unmatched "\E" codes that can lead to the compiled bytecode being corrupted (CVE-2007-1659). Further improper calculations of memory boundaries were reported when matching certain input bytes against regex patterns in non UTF-8 mode (CVE-2007-1661) and when searching for unmatched brackets or parentheses (CVE-2007-1662). PCRE does not properly handle "\P" and "\P{x}" sequences which can lead to heap-based buffer overflows or trigger the execution of infinite loops (CVE-2007-4767), PCRE is also prone to an error when optimizing character classes containing a singleton UTF-8 sequence which might lead to a heap-based buffer overflow (CVE-2007-4768).

Chris Evans also reported multiple integer overflow vulnerabilities in PCRE when processing a large number of named subpatterns ("name_count") or long subpattern names ("max_name_size") (CVE-2006-7227), and via large "min", "max", or "duplength" values (CVE-2006-7228) both possibly leading to buffer overflows. Another vulnerability was reported when compiling patterns where the "-x" or "-i" UTF-8 options change within the pattern, which might lead to improper memory calculations (CVE-2006-7230).

Workaround

There is no known workaround at this time.

Resolution

All PCRE users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libpcre-7.3-r1"

Therefore, this\nupdate contains version 7.3, with special patches to improve the\ncompatibility with the older versions.  As a result, extra care is\nnecessary when applying this update. \n\nThe Common Vulnerabilities and Exposures project identifies the\nfollowing problems:\n\nCVE-2007-1659\n\n    Unmatched \\Q\\E sequences with orphan \\E codes can cause the compiled\n    regex to become desynchronized, resulting in corrupt bytecode that may\n    result in multiple exploitable conditions. \n\nCVE-2007-1660\n \n    Multiple forms of character class had their sizes miscalculated on\n    initial passes, resulting in too little memory being allocated. \n\nCVE-2007-1661\n\n    Multiple patterns of the form  \\X?\\d or \\P{L}?\\d in non-UTF-8 mode\n    could backtrack before the start of the string, possibly leaking\n    information from the address space, or causing a crash by reading out\n    of bounds. \n\nCVE-2007-1662\n\n    A number of routines can be fooled into reading past the end of an\n    string looking for unmatched parentheses or brackets, resulting in a\n    denial of service. \n\nCVE-2007-4766\n\n    Multiple integer overflows in the processing of escape sequences could\n    result in heap overflows or out of bounds reads/writes. \n\nCVE-2007-4767\n\n    Multiple infinite loops and heap overflows were disovered in the\n    handling of \\P and \\P{x} sequences, where the length of these\n    non-standard operations was mishandled. \n\nCVE-2007-4768\n\n    Character classes containing a lone unicode sequence were incorrectly\n    optimised, resulting in a heap overflow. \n\nFor the stable distribution (etch), these problems have been fixed in\nversion 6.7+7.4-2. \n\nFor the old stable distribution (sarge), these problems have been fixed in\nversion 4.5+7.4-1. \n\nFor the unstable distribution (sid), these problems have been fixed in\nversion 7.3-1.

=========================================================== \nUbuntu Security Notice USN-547-1          November 27, 2007\npcre3 vulnerabilities\nCVE-2007-1659, CVE-2007-1660, CVE-2007-1661, CVE-2007-1662,\nCVE-2007-4766, CVE-2007-4767, CVE-2007-4768\n===========================================================\n\nA security issue affects the following Ubuntu releases:\n\nUbuntu 6.06 LTS\nUbuntu 6.10\nUbuntu 7.04\nUbuntu 7.10\n\nThis advisory also applies to the corresponding versions of\nKubuntu, Edubuntu, and Xubuntu. \n\nThe problem can be corrected by upgrading your system to the\nfollowing package versions:\n\nUbuntu 6.06 LTS:\n  libpcre3                        7.4-0ubuntu0.6.06.1\n  libpcrecpp0                     7.4-0ubuntu0.6.06.1\n\nUbuntu 6.10:\n  libpcre3                        7.4-0ubuntu0.6.10.1\n  libpcrecpp0                     7.4-0ubuntu0.6.10.1\n\nUbuntu 7.04:\n  libpcre3                        7.4-0ubuntu0.7.04.1\n  libpcrecpp0                     7.4-0ubuntu0.7.04.1\n\nUbuntu 7.10:\n  libpcre3                        7.4-0ubuntu0.7.10.1\n  libpcrecpp0                     7.4-0ubuntu0.7.10.1\n\nAfter a standard system upgrade you need to reboot your computer to\neffect the necessary changes. \n\nDue to the large internal code changes needed to solve outstanding flaws,\nit was not possible to backport all the upstream security fixes to the\nearlier released versions. \n\nDetails follow:\n\nTavis Ormandy and Will Drewry discovered multiple flaws in the regular\nexpression handling of PCRE. He reported an error when processing \"\\Q\\E\" sequences with\nunmatched \"\\E\" codes that can lead to the compiled bytecode being\ncorrupted (CVE-2007-1659). Further improper calculations of\nmemory boundaries were reported when matching certain input bytes\nagainst regex patterns in non UTF-8 mode (CVE-2007-1661) and when\nsearching for unmatched brackets or parentheses (CVE-2007-1662). PCRE does not properly handle \"\\P\" and\n\"\\P{x}\" sequences which can lead to heap-based buffer overflows or\ntrigger the execution of infinite loops (CVE-2007-4767), PCRE is also\nprone to an error when optimizing character classes containing a\nsingleton UTF-8 sequence which might lead to a heap-based buffer\noverflow (CVE-2007-4768). \n\nChris Evans also reported multiple integer overflow vulnerabilities in\nPCRE when processing a large number of named subpatterns (\"name_count\")\nor long subpattern names (\"max_name_size\") (CVE-2006-7227), and via\nlarge \"min\", \"max\", or \"duplength\" values (CVE-2006-7228) both possibly\nleading to buffer overflows. Another vulnerability was reported when\ncompiling patterns where the \"-x\" or \"-i\" UTF-8 options change within\nthe pattern, which might lead to improper memory calculations\n(CVE-2006-7230). \n\nWorkaround\n==========\n\nThere is no known workaround at this time. \n\nResolution\n==========\n\nAll PCRE users should upgrade to the latest version:\n\n    # emerge --sync\n    # emerge --ask --oneshot --verbose \"\u003e=dev-libs/libpcre-7.3-r1\"\n\nReferences\n==========\n\n  [ 1 ] CVE-2006-7227\n        http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-7227\n  [ 2 ] CVE-2006-7228\n        http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-7228\n  [ 3 ] CVE-2006-7230\n        http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-7230\n  [ 4 ] CVE-2007-1659\n        http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1659\n  [ 5 ] CVE-2007-1660\n        http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1660\n  [ 6 ] CVE-2007-1661\n        http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1661\n  [ 7 ] CVE-2007-1662\n        http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1662\n  [ 8 ] CVE-2007-4766\n        http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4766\n  [ 9 ] CVE-2007-4767\n        http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4767\n  [ 10 ] CVE-2007-4768\n         http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4768\n\nAvailability\n============\n\nThis GLSA and any updates to it are available for viewing at\nthe Gentoo Security Website:\n\n  http://security.gentoo.org/glsa/glsa-200711-30.xml\n\nConcerns?\n=========\n\nSecurity is a primary focus of Gentoo Linux and ensuring the\nconfidentiality and security of our users machines is of utmost\nimportance to us.

Vulnerability from variot - Updated: 2025-12-22 20:26

libpcre in PCRE before 8.44 allows an integer overflow via a large number after a (?C substring. PCRE is an open source regular expression library written in C language by Philip Hazel software developer. An input validation error vulnerability exists in libpcre in versions prior to PCRE 8.44. An attacker could exploit this vulnerability to execute arbitrary code or cause an application to crash on the system with a large number of requests. Bugs fixed (https://bugzilla.redhat.com/):

Summary:

Gatekeeper Operator v0.2

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

  1. Description:

Gatekeeper Operator v0.2

Gatekeeper is an open source project that applies the OPA Constraint Framework to enforce policies on your Kubernetes clusters.

This advisory contains the container images for Gatekeeper that include security updates, and container upgrades.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Note: Gatekeeper support from the Red Hat support team is limited cases where it is integrated and used with Red Hat Advanced Cluster Management for Kubernetes. For support options for any other use, see the Gatekeeper open source project website at: https://open-policy-agent.github.io/gatekeeper/website/docs/howto/.

Security updates:

  • golang.org/x/crypto: empty plaintext packet causes panic (CVE-2021-43565)

  • golang: crypto/elliptic IsOnCurve returns true for invalid field elements (CVE-2022-23806)

  • Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied.

The requirements to apply the upgraded images are different whether or not you used the operator. Complete the following steps, depending on your installation:

    • Upgrade gatekeeper operator: The gatekeeper operator that is installed by the gatekeeper operator policy has installPlanApproval set to Automatic. This setting means the operator will be upgraded automatically when there is a new version of the operator. No further action is required for upgrade. If you changed the setting for installPlanApproval to manual, then you must view each cluster to manually approve the upgrade to the operator.
    • Upgrade gatekeeper without the operator: The gatekeeper version is specified as part of the Gatekeeper CR in the gatekeeper operator policy. To upgrade the gatekeeper version: a) Determine the latest version of gatekeeper by visiting: https://catalog.redhat.com/software/containers/rhacm2/gatekeeper-rhel8/5fadb4a18d9a79d2f438a5d9. b) Click the tag dropdown, and find the latest static tag. An example tag is 'v3.3.0-1'. c) Edit the gatekeeper operator policy and update the image tag to use the latest static tag. For example, you might change this line to image: 'registry.redhat.io/rhacm2/gatekeeper-rhel8:v3.3.0-1'.

Refer to https://open-policy-agent.github.io/gatekeeper/website/docs/howto/ for additional information.

Summary:\n\nGatekeeper Operator v0.2\n\nRed Hat Product Security has rated this update as having a security impact\nof Moderate. A Common Vulnerability Scoring System (CVSS) base score,\nwhich gives a detailed severity rating, is available for each vulnerability\nfrom the CVE link(s) in the References section. \n\n2. Description:\n\nGatekeeper Operator v0.2\n\nGatekeeper is an open source project that applies the OPA Constraint\nFramework to enforce policies on your Kubernetes clusters. \n\nThis advisory contains the container images for Gatekeeper that include\nsecurity updates, and container upgrades. \n\nRed Hat Product Security has rated this update as having a security impact\nof Moderate. A Common Vulnerability Scoring System (CVSS) base score,\nwhich gives a detailed severity rating, is available for each vulnerability\nfrom the CVE link(s) in the References section. \n\nNote: Gatekeeper support from the Red Hat support team is limited cases\nwhere it is integrated and used with Red Hat Advanced Cluster Management\nfor Kubernetes. For support options for any other use, see the Gatekeeper\nopen source project website at:\nhttps://open-policy-agent.github.io/gatekeeper/website/docs/howto/. \n\nSecurity updates:\n\n* golang.org/x/crypto: empty plaintext packet causes panic (CVE-2021-43565)\n\n* golang: crypto/elliptic IsOnCurve returns true for invalid field elements\n(CVE-2022-23806)\n\n3. Solution:\n\nBefore applying this update, make sure all previously released errata\nrelevant to your system have been applied. \n\nThe requirements to apply the upgraded images are different whether or not\nyou\nused the operator. Complete the following steps, depending on your\ninstallation:\n\n- - Upgrade gatekeeper operator:\nThe gatekeeper operator that is installed by the gatekeeper operator policy\nhas\n`installPlanApproval` set to `Automatic`. This setting means the operator\nwill\nbe upgraded automatically when there is a new version of the operator. No\nfurther action is required for upgrade. If you changed the setting for\n`installPlanApproval` to `manual`, then you must view each cluster to\nmanually\napprove the upgrade to the operator. \n\n- - Upgrade gatekeeper without the operator:\nThe gatekeeper version is specified as part of the Gatekeeper CR in the\ngatekeeper operator policy. To upgrade the gatekeeper version:\na) Determine the latest version of gatekeeper by visiting:\nhttps://catalog.redhat.com/software/containers/rhacm2/gatekeeper-rhel8/5fadb4a18d9a79d2f438a5d9. \nb) Click the tag dropdown, and find the latest static tag. An example tag\nis\n\u0027v3.3.0-1\u0027. \nc) Edit the gatekeeper operator policy and update the image tag to use the\nlatest static tag. For example, you might change this line to image:\n\u0027registry.redhat.io/rhacm2/gatekeeper-rhel8:v3.3.0-1\u0027. \n\nRefer to https://open-policy-agent.github.io/gatekeeper/website/docs/howto/\nfor additional information. \n\n4. Bugs fixed (https://bugzilla.redhat.com/):\n\n2030787 - CVE-2021-43565 golang.org/x/crypto: empty plaintext packet causes panic\n2053429 - CVE-2022-23806 golang: crypto/elliptic IsOnCurve returns true for invalid field elements\n\n5.
