Description Jan Lieskovsky 2013-02-12 11:03:04 UTC

A stack-based buffer overflow flaw was found in the way OpenConnect, a client for Cisco's "AnyConnect" VPN, performed processing of certain host names, paths, or cookie lists, received from the VPN gateway. A remote VPN gateway could provide a specially-crafted host name, path or cookie list that, when processed by the openconnect client would lead to openconnect executable crash.
