Permissions, Privileges, and Access Controls
mount in util-linux 2.19 and earlier does not remove the /etc/mtab.tmp file after a failed attempt to add a mount entry, which allows local users to trigger corruption of the /etc/mtab file via multiple invocations.
CWE-264 - Permissions Privileges and Access Controls
CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
