CUPS contains a stripped down version of xpdf. Recent issues have been found in xpdf 2 that can result in integer overflows causing bad memory allocation or out of bounds writes. It's not expected these can cause arbitrary code execution, more likely to be DoS crashers. Embargoed until October 20th 1400UTC Patch to follow CVE names to follow
Created attachment 105056 [details] xpdf 2 patch (will require changes to apply against Cups)
CAN-2004-0888. Actually my comment about arbitrary code execution is inaccurate since the flaws could allow you to write an arbitrary byte at an (almost) arbitrary location. This could possibly lead to privilege escalation (although it would be hard to do, especially with Exec-shield).
