Summary

Details

Integer overflow in the _IO_wstr_overflow function in libio/wstrops.c in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors related to computing a size in bytes, which triggers a heap-based buffer overflow.

Severity

8.1 (High)

Summary

eglibc, glibc vulnerabilities

Details

It was discovered that the GNU C Library incorrectly handled the strxfrm() function. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8982)

It was discovered that an integer overflow existed in the _IO_wstr_overflow() function of the GNU C Library. An attacker could use this to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8983)

It was discovered that the fnmatch() function in the GNU C Library did not properly handle certain malformed patterns. An attacker could use this to cause a denial of service. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8984)

Alexander Cherepanov discovered a stack-based buffer overflow in the glob implementation of the GNU C Library. An attacker could use this to specially craft a directory layout and cause a denial of service. (CVE-2016-1234)

Florian Weimer discovered a NULL pointer dereference in the DNS resolver of the GNU C Library. An attacker could use this to cause a denial of service. (CVE-2015-5180)

Michael Petlan discovered an unbounded stack allocation in the getaddrinfo() function of the GNU C Library. An attacker could use this to cause a denial of service. (CVE-2016-3706)

Aldy Hernandez discovered an unbounded stack allocation in the sunrpc implementation in the GNU C Library. An attacker could use this to cause a denial of service. (CVE-2016-4429)

Tim Ruehsen discovered that the getaddrinfo() implementation in the GNU C Library did not properly track memory allocations. An attacker could use this to cause a denial of service. This issue only affected Ubuntu 16.04 LTS. (CVE-2016-5417)

Andreas Schwab discovered that the GNU C Library on ARM 32-bit platforms did not properly set up execution contexts. An attacker could use this to cause a denial of service. (CVE-2016-6323)
