Debian Security Advisory DSA-5522-1 security@debian.org https://www.debian.org/security/ Markus Koschany October 10, 2023 https://www.debian.org/security/faq
Package : tomcat9 CVE ID : CVE-2023-24998 CVE-2023-41080 CVE-2023-42795 CVE-2023-44487 CVE-2023-45648
Several security vulnerabilities have been discovered in the Tomcat servlet and JSP engine.
CVE-2023-24998
Denial of service. Tomcat uses a packaged renamed copy of Apache Commons
FileUpload to provide the file upload functionality defined in the Jakarta
Servlet specification. Apache Tomcat was, therefore, also vulnerable to the
Commons FileUpload vulnerability CVE-2023-24998 as there was no limit to
the number of request parts processed. This resulted in the possibility of
an attacker triggering a DoS with a malicious upload or series of uploads.
CVE-2023-41080
Open redirect. If the ROOT (default) web application is configured to use
FORM authentication then it is possible that a specially crafted URL could
be used to trigger a redirect to an URL of the attackers choice.
CVE-2023-42795
Information Disclosure. When recycling various internal objects, including
the request and the response, prior to re-use by the next request/response,
an error could cause Tomcat to skip some parts of the recycling process
leading to information leaking from the current request/response to the
next.
CVE-2023-44487
DoS caused by HTTP/2 frame overhead (Rapid Reset Attack)
CVE-2023-45648
Request smuggling. Tomcat did not correctly parse HTTP trailer headers. A
specially crafted, invalid trailer header could cause Tomcat to treat a
single request as multiple requests leading to the possibility of request
smuggling when behind a reverse proxy.
For the oldstable distribution (bullseye), these problems have been fixed in version 9.0.43-2~deb11u7.
We recommend that you upgrade your tomcat9 packages.
For the detailed security status of tomcat9 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/tomcat9

Tomcat uses a packaged renamed copy of Apache Commons\n FileUpload to provide the file upload functionality defined in the Jakarta\n Servlet specification. Apache Tomcat was, therefore, also vulnerable to the\n Commons FileUpload vulnerability CVE-2023-24998 as there was no limit to\n the number of request parts processed. This resulted in the possibility of\n an attacker triggering a DoS with a malicious upload or series of uploads. \n\nCVE-2023-41080\n\n Open redirect. If the ROOT (default) web application is configured to use\n FORM authentication then it is possible that a specially crafted URL could\n be used to trigger a redirect to an URL of the attackers choice. \n\nCVE-2023-42795\n\n Information Disclosure. When recycling various internal objects, including\n the request and the response, prior to re-use by the next request/response,\n an error could cause Tomcat to skip some parts of the recycling process\n leading to information leaking from the current request/response to the\n next. \n\nCVE-2023-44487\n\n DoS caused by HTTP/2 frame overhead (Rapid Reset Attack)\n\nCVE-2023-45648\n\n Request smuggling. Tomcat did not correctly parse HTTP trailer headers. A\n specially crafted, invalid trailer header could cause Tomcat to treat a\n single request as multiple requests leading to the possibility of request\n smuggling when behind a reverse proxy. \n\nFor the oldstable distribution (bullseye), these problems have been fixed\nin version 9.0.43-2~deb11u7. \n\nWe recommend that you upgrade your tomcat9 packages. \n\nFor the detailed security status of tomcat9 please refer to\nits security tracker page at:\nhttps://security-tracker.debian.org/tracker/tomcat9\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\ne3g3nA1rbB1jlx6cvPqWBFItXW8800mJ0CXHb8EN8jKdB5BnooY=\n=6KYM\n-----END PGP SIGNATURE-----\n. \n\n\n\n\nDescription:\n\nVarnish Cache is a high-performance HTTP accelerator.

Title
Denial of Service through Data corruption in gRPC-C++
Summary
There exists a denial of service through Data corruption in gRPC-C++ - gRPC-C++ servers with transmit zero copy enabled through the channel arg GRPC_ARG_TCP_TX_ZEROCOPY_ENABLED can experience data corruption issues. The data sent by the application may be corrupted before transmission over the network thus leading the receiver to receive an incorrect set of bytes causing RPC requests to fail. We recommend upgrading past commit e9046b2bbebc0cb7f5dc42008f807f6c7e98e791

CVE-2024-7246 (GCVE-0-2024-7246)
Vulnerability from nvd – Published: 2024-08-06 10:14 – Updated: 2024-08-06 13:17

Title
HPACK table poisoning in gRPC C++, Python & Ruby
Summary
It's possible for a gRPC client communicating with a HTTP/2 proxy to poison the HPACK table between the proxy and the backend such that other clients see failed requests. It's also possible to use this vulnerability to leak other clients HTTP header keys, but not values.
This occurs because the error status for a misencoded header is not cleared between header reads, resulting in subsequent (incrementally indexed) added headers in the first request being poisoned until cleared from the HPACK table.
Please update to a fixed version of gRPC as soon as possible. This bug has been fixed in 1.58.3, 1.59.5, 1.60.2, 1.61.3, 1.62.3, 1.63.2, 1.64.3, 1.65.4.

Title
Denial-of-Service in gRPC
Summary
gRPC contains a vulnerability that allows hpack table accounting errors could lead to unwanted disconnects between clients and servers in exceptional cases/ Three vectors were found that allow the following DOS attacks:
- Unbounded memory buffering in the HPACK parser
- Unbounded CPU consumption in the HPACK parser
The unbounded CPU consumption is down to a copy that occurred per-input-block in the parser, and because that could be unbounded due to the memory copy bug we end up with an O(n^2) parsing loop, with n selected by the client.
The unbounded memory buffering bugs:
- The header size limit check was behind the string reading code, so we needed to first buffer up to a 4 gigabyte string before rejecting it as longer than 8 or 16kb.
- HPACK varints have an encoding quirk whereby an infinite number of 0’s can be added at the start of an integer. gRPC’s hpack parser needed to read all of them before concluding a parse.
- gRPC’s metadata overflow check was performed per frame, so that the following sequence of frames could cause infinite buffering: HEADERS: containing a: 1 CONTINUATION: containing a: 2 CONTINUATION: containing a: 3 etc…

Title
Information leak in gRPC
Summary
When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame. This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables between sender and receiver. If leveraged, say, between a proxy and a backend, this could lead to requests from the proxy being interpreted as containing headers from different proxy clients - leading to an information leak that can be used for privilege escalation or data exfiltration.

CVE-2023-1428 (GCVE-0-2023-1428)
Vulnerability from nvd – Published: 2023-06-09 10:46 – Updated: 2024-09-26 18:58
VLAI?
Title
Denial-of-Service in gRPC
Summary
There exists an vulnerability causing an abort() to be called in gRPC.
The following headers cause gRPC's C++ implementation to abort() when called via http2:
te: x (x != trailers)
:scheme: x (x != http, https)
grpclb_client_stats: x (x == anything)
On top of sending one of those headers, a later header must be sent that gets the total header size past 8KB. We recommend upgrading past git commit 2485fa94bd8a723e5c977d55a3ce10b301b437f8 or v1.53 and above.

Title
Denial of Service through Data corruption in gRPC-C++
Summary

CVE-2024-7246 (GCVE-0-2024-7246)
Vulnerability from cvelistv5 – Published: 2024-08-06 10:14 – Updated: 2024-08-06 13:17
VLAI?
Title
HPACK table poisoning in gRPC C++, Python & Ruby
Summary
It's possible for a gRPC client communicating with a HTTP/2 proxy to poison the HPACK table between the proxy and the backend such that other clients see failed requests. It's also possible to use this vulnerability to leak other clients HTTP header keys, but not values.
This occurs because the error status for a misencoded header is not cleared between header reads, resulting in subsequent (incrementally indexed) added headers in the first request being poisoned until cleared from the HPACK table.
Please update to a fixed version of gRPC as soon as possible. This bug has been fixed in 1.58.3, 1.59.5, 1.60.2, 1.61.3, 1.62.3, 1.63.2, 1.64.3, 1.65.4.

Title
Denial-of-Service in gRPC
Summary
gRPC contains a vulnerability that allows hpack table accounting errors could lead to unwanted disconnects between clients and servers in exceptional cases/ Three vectors were found that allow the following DOS attacks:
- Unbounded memory buffering in the HPACK parser
- Unbounded CPU consumption in the HPACK parser
The unbounded CPU consumption is down to a copy that occurred per-input-block in the parser, and because that could be unbounded due to the memory copy bug we end up with an O(n^2) parsing loop, with n selected by the client.
The unbounded memory buffering bugs:
- The header size limit check was behind the string reading code, so we needed to first buffer up to a 4 gigabyte string before rejecting it as longer than 8 or 16kb.
- HPACK varints have an encoding quirk whereby an infinite number of 0’s can be added at the start of an integer. gRPC’s hpack parser needed to read all of them before concluding a parse.
- gRPC’s metadata overflow check was performed per frame, so that the following sequence of frames could cause infinite buffering: HEADERS: containing a: 1 CONTINUATION: containing a: 2 CONTINUATION: containing a: 3 etc…

Vulnerability from cvelistv5 – Published: 2023-06-09 10:54 – Updated: 2024-09-26 19:12

Title
Information leak in gRPC
Summary
When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame. This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables between sender and receiver. If leveraged, say, between a proxy and a backend, this could lead to requests from the proxy being interpreted as containing headers from different proxy clients - leading to an information leak that can be used for privilege escalation or data exfiltration. We recommend upgrading beyond the commit contained in https://github.com/grpc/grpc/pull/33005 https://github.com/grpc/grpc/pull/33005

Title
Denial-of-Service in gRPC
Summary
There exists an vulnerability causing an abort() to be called in gRPC.
The following headers cause gRPC's C++ implementation to abort() when called via http2:
te: x (x != trailers)
:scheme: x (x != http, https)
grpclb_client_stats: x (x == anything)
On top of sending one of those headers, a later header must be sent that gets the total header size past 8KB. We recommend upgrading past git commit 2485fa94bd8a723e5c977d55a3ce10b301b437f8 or v1.53 and above.
