Name of the Vulnerable Software and Affected Versions glibc versions prior to 2.21

Description The issue is caused by an integer overflow in the strxfrm function, which can be triggered by a long string. This can lead to a stack-based buffer overflow, potentially allowing context-dependent attackers to cause a denial of service or possibly execute arbitrary code.

Recommendations For versions prior to 2.21, update to version 2.21 or later to resolve the issue. As a temporary workaround, consider restricting the use of the strxfrm function to minimize the risk of exploitation. Avoid using long strings that could trigger the integer overflow until the issue is resolved.
