Ubuntu 14.04 LTS / 16.04 LTS : Git vulnerability (USN-3438-1)

high Nessus Plugin ID 103691

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3438-1 advisory.

It was discovered that Git incorrectly handled certain subcommands such as cvsserver. A remote attacker could possibly use this issue via shell metacharacters in modules names to execute arbitrary code.

This update also removes the cvsserver subcommand from git-shell by default.

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.
