critical Nessus Plugin ID 125476

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3994-1 advisory.

 It was discovered that gnome-desktop incorrectly confined thumbnailers. If a user were tricked into downloading a malicious image file, a remote attacker could possibly combine this issue with another vulnerability to escape the sandbox and execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution
