Ubuntu 14.04 LTS : APT vulnerability (USN-2353-1)

high Nessus Plugin ID 77816

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2353-1 advisory.

 It was discovered that APT incorrectly handled certain http URLs. If a remote attacker were able to perform a machine-in-the-middle attack, this flaw could be exploited to cause APT to crash, resulting in a denial of service, or possibly execute arbitrary code. The default compiler options for affected releases should reduce the vulnerability to a denial of service. (CVE-2014-6273)

 In addition, this update fixes regressions introduced by the USN-2348-1 security update: APT incorrectly handled file:/// sources on a different partition, incorrectly handled Dir::state::lists set to a relative path, and incorrectly handled cdrom: sources.

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.
