medium Nessus Plugin ID 136608

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

It was discovered that APT incorrectly handled certain filenames during package installation. If an attacker could provide a specially crafted package to be installed by the system administrator, this could cause APT to crash.

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.

Solution

Update the affected packages.
