USN-3387-1: Git vulnerability

11 August 2017

Git could be made run programs as your login if it opened a specially crafted git repository.

Releases

Packages

  • git - fast, scalable, distributed revision control system

Details

Brian Neel, Joern Schneeweisz, and Jeff King discovered that Git did
not properly handle host names in 'ssh://' URLs. A remote attacker
could use this to construct a git repository that when accessed could
run arbitrary code with the privileges of the user.

Update instructions

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

Ubuntu 17.04
Ubuntu 16.04
Ubuntu 14.04

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