USN-3387-1: Git vulnerability
Ubuntu Security Notice USN-3387-1
10th August, 2017
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.04
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
Git could be made run programs as your login if it opened a specially crafted git repository.
- git - fast, scalable, distributed revision control system
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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 17.04:
- git 1:2.11.0-2ubuntu0.2
- Ubuntu 16.04 LTS:
- git 1:2.7.4-0ubuntu1.2
- Ubuntu 14.04 LTS:
- git 1:1.9.1-1ubuntu0.6
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
