Descriptions
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.
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. 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.
