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)
