Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS : Flatpak and Bubblewrap vulnerability (USN-7046-1)

critical Nessus Plugin ID 207953

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-7046-1 advisory.

 It was discovered that Flatpak incorrectly handled certain persisted directories. An attacker could possibly use this issue to read and write files in locations it would not normally have access to. A patch was also needed to Bubblewrap in order to avoid race conditions caused by this fix.

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

Update the affected packages.
