USN-2835-1: Git vulnerability

15 December 2015

Git could be made to run programs as your login if it processed an untrusted repository.

Releases

Packages

  • git - fast, scalable, distributed revision control system

Details

Blake Burkhart discovered that the Git git-remote-ext helper incorrectly
handled recursive clones of git repositories. A remote attacker could
possibly use this issue to execute arbitrary code by injecting commands
via crafted URLs.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 15.10
Ubuntu 15.04
Ubuntu 14.04
Ubuntu 12.04

In general, a standard system update will make all the necessary changes.
