"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."
