Name of the Vulnerable Software and Affected Versions glibc versions prior to 2.20

Description The issue is related to the get contents function in the Name Service Switch (NSS) in GNU C Library, which might allow local users to cause a denial of service or gain privileges via a long line in the NSS files database.

Recommendations For versions prior to 2.20, update to version 2.20 or later to resolve the issue. As a temporary workaround, consider restricting access to the NSS files database to minimize the risk of exploitation.
