Ubuntu 6.06 LTS / 6.10 / 7.04 : util-linux vulnerability (USN-533-1)

medium Nessus Plugin ID 28139
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Ubuntu host is missing one or more security-related patches.


Ludwig Nussel discovered that mount and umount did not properly drop privileges when using helper programs. Local attackers may be able to bypass security restrictions and gain root privileges using programs such as mount.nfs or mount.cifs.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected packages.
