Description Jan Lieskovsky 2013-04-23 14:55:54 UTC
A stack-based buffer overflow flaw was found in the way Tinc, a virtual private network (VPN) daemon that uses tunnelling and encryption to create a secure private network between hosts on the Internet, processed certain TCP packets. A remote, authenticated attacker could send a specially-crafted TCP packet that, when processed would lead to tincd daemon termination (denial of service).
