Name of the Vulnerable Software and Affected Versions glibc versions prior to 2.22

Description The issue in the GNU C Library (glibc) might allow context-dependent attackers to cause a denial of service, resulting in an application crash. This can be demonstrated by using the fnmatch library function with a specific pattern.

Recommendations For versions prior to 2.22, update to version 2.22 or later to resolve the issue. As a temporary workaround, consider avoiding the use of the fnmatch library function with the **(!() pattern until a patch is available.
