CVE-2015-20109

end_pattern (called from internal_fnmatch) in the GNU C Library (aka glibc or libc6) before 2.22 might allow context-dependent attackers to cause a denial of service (application crash), as demonstrated by use of the fnmatch library function with the **(!() pattern. NOTE: this is not the same as CVE-2015-8984; also, some Linux distributions have fixed CVE-2015-8984 but have not fixed this additional fnmatch issue.

USN-6762-1 — eglibc, glibc vulnerabilities

Affected: Ubuntu:Pro:14.04:LTS: eglibc, Ubuntu:Pro:16.04:LTS: glibc, Ubuntu:Pro:18.04:LTS: glibc

It was discovered that GNU C Library incorrectly handled netgroup requests. An attacker could possibly use this issue to cause a crash or execute arbitrary code. This issue only affected Ubuntu 14.04 LTS. (CVE-2014-9984)

It was discovered that GNU C Library might allow context-dependent attackers to cause a denial of service. This issue only affected Ubuntu 14.04 LTS. (CVE-2015-20109)

It was discovered that GNU C Library when processing very long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit architectures, leading to a stack-based buffer overflow and, potentially, arbitrary code execution. This issue only affected Ubuntu 14.04 LTS. (CVE-2018-11236)

It was discovered that the GNU C library getcwd function incorrectly handled buffers. An attacker could use this issue to cause the GNU C Library to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS. (CVE-2021-3999)

Charles Fol discovered that the GNU C Library iconv feature incorrectly handled certain input sequences. An attacker could use this issue to cause the GNU C Library to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2024-2961)
