Published: 31 December 2015

The fnmatch function 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) via a malformed pattern, which triggers an out-of-bounds read.

From the Ubuntu security team

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.
