Ubuntu 14.04 LTS / 16.04 LTS / 17.04 : bzr vulnerability (USN-3411-1)

High Nessus Plugin ID 102976


The remote Ubuntu host is missing one or more security-related patches.


Adam Collard discovered that Bazaar did not properly handle host names in 'bzr+ssh://' URLs. A remote attacker could use this to construct a bazaar repository URL that when accessed could run arbitrary code with the privileges of the user.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected bzr and / or python-bzrlib packages.
