USN-3399-1: cvs vulnerability

21 August 2017

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



  • cvs - Concurrent Versions System


Hank Leininger discovered that cvs did not properly handle SSH
for remote repositories. A remote attacker could use this to
construct a cvs 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.
