Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : git vulnerability (USN-3791-1)

High Nessus Plugin ID 118083

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

It was discovered that git did not properly validate git submodule urls or paths. A remote attacker could possibly use this to craft a git repository that causes arbitrary code execution when recursive operations are used.

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 git package.
