Ubuntu 16.04 LTS / 18.04 LTS : Git vulnerability (USN-4334-1)

high Nessus Plugin ID 135895

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

Carlo Arenas discovered that Git incorrectly handled certain URLs containing newlines, empty hosts, or lacking a scheme. A remote attacker could possibly use this issue to trick Git into returning credential information for a wrong host.

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.
