Discussion

util-linux Package 'mount' and 'umount' Multiple Local Denial of Service Vulnerabilities

The 'util-linux' package is prone to multiple local denial-of-service vulnerabilities that affect the 'mount' and 'umount' programs.

A local attacker can exploit these issues to corrupt the '/etc/mtab' file or create a stale lock file (/etc/mtab~), which prevents other users from mounting and unmounting file systems. This causes a denial-of-service condition.
