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