FreeBSD : libproxy -- stack-based buffer overflow (3b5c2362-bd07-11e5-b7ef-5453ed2e2b49)

Critical Nessus Plugin ID 87982


The remote FreeBSD host is missing one or more security-related updates.


Tomas Hoger reports :

A buffer overflow flaw was discovered in the libproxy's url::get_pac() used to download proxy.pac proxy auto-configuration file. A malicious host hosting proxy.pac, or a man in the middle attacker, could use this flaw to trigger a stack-based buffer overflow in an application using libproxy, if proxy configuration instructed it to download proxy.pac file from a remote HTTP server.


Update the affected packages.
