Scientific Linux Security Update : cups-filters on SL7.x x86_64

High Nessus Plugin ID 87553


The remote Scientific Linux host is missing one or more security updates.


A heap-based buffer overflow flaw and an integer overflow flaw leading to a heap-based buffer overflow were discovered in the way the texttopdf utility of cups-filter processed print jobs with a specially crafted line size. An attacker able to submit print jobs could use these flaws to crash texttopdf or, possibly, execute arbitrary code with the privileges of the 'lp' user. (CVE-2015-3258, CVE-2015-3279)

Notably, this update also fixes the following bug :

- Previously, when polling CUPS printers from a CUPS server, when a printer name contained an underscore (_), the client displayed the name containing a hyphen (-) instead. This made the print queue unavailable. With this update, CUPS allows the underscore character in printer names, and printers appear as shown on the CUPS server as expected.

In addition, this update adds the following enhancement :

- Now, the information from local and remote CUPS servers is cached during each poll, and the CUPS server load is reduced.


Update the affected packages.
