Ubuntu 12.04 LTS / 12.10 / 13.04 / 13.10 : puppet regression (USN-2077-2)

medium Nessus Plugin ID 71895

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

USN-2077-1 fixed a vulnerability in Puppet. The upstream patch introduced a regression resulting in the default file mode being incorrect. This update fixes the problem.

We apologize for the inconvenience.

It was discovered that Puppet incorrectly handled temporary files. A local attacker could possibly use this issue to overwrite arbitrary files. In the default installation of Ubuntu, this should be prevented by the Yama link restrictions.

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.

Solution

Update the affected puppet-common package.
