git vulnerability

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.

Software description

  • 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.
