Name of the Vulnerable Software and Affected Versions util-linux versions prior to 2.22.2

Description The issue concerns multiple vulnerabilities in the util-linux package that can be exploited locally, potentially leading to breaches of confidentiality, integrity, and availability of protected information. A specific problem in util-linux versions 2.19 and earlier involves the mount function attempting to append to the /etc/mtab.tmp file without checking for resource limits, which can lead to corruption of the /etc/mtab file if a user triggers the issue with a process that has a small RLIMIT FSIZE value.

Recommendations For util-linux versions prior to 2.22.2, update to version 2.22.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the mount function to minimize the risk of exploitation.
