Summary

cups regression

Details

USN-6844-1 fixed vulnerabilities in the CUPS package. The update lead to the discovery of a regression in CUPS with regards to how the cupsd daemon handles Listen configuration directive. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details: Rory McNamara discovered that when starting the cupsd server with a Listen configuration item, the cupsd process fails to validate if bind call passed. An attacker could possibly trick cupsd to perform an arbitrary chmod of the provided argument, providing world-writable access to the target.
