Scientific Linux Security Update : libproxy on SL6.x i386/x86_64

Critical Nessus Plugin ID 62933


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


A buffer overflow flaw was found in the way libproxy handled the downloading of proxy auto-configuration (PAC) files. A malicious server hosting a PAC file or a man-in-the-middle attacker could use this flaw to cause an application using libproxy to crash or, possibly, execute arbitrary code, if the proxy settings obtained by libproxy (from the environment or the desktop environment settings) instructed the use of a PAC proxy configuration. (CVE-2012-4505)

All applications using libproxy must be restarted for this update to take effect.


Update the affected packages.
