USN-3387-1: Git vulnerability Ubuntu Security Notice USN-3387-1 10th August, 2017 git vulnerability A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 17.04 Ubuntu 16.04 LTS Ubuntu 14.04 LTS Summary Git could be made run programs as your login if it opened a specially crafted git repository. Software description git – fast, scalable, distributed revision control system Details Brian Neel, Joern Schneeweisz, and Jeff King discovered that Git didnot properly handle host names in 'ssh://' URLs. A remote attackercould use this to construct a git repository that when accessed couldrun arbitrary code with the privileges of the user. Update instructions 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.
