Summary

libproxy is a library that handles all the details of proxy configuration.
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)
This issue was discovered by the Red Hat Security Response Team.
Users of libproxy should upgrade to these updated packages, which contain a backported patch to correct this issue. All applications using libproxy must be restarted for this update to take effect.
