Description Jan Lieskovsky 2011-09-14 17:41:25 UTC 
A heap-based buffer overflow flaw was found in the way bgpd daemon of the Quagga routing suite processed BGP UPDATE messages containing unknown AS_PATH in Extended Communities Path Attribute. A configured BGP peer could use this flaw to cause the master BGP daemon (bgpd) to crash, or, potentially execute arbitrary code with the privileges of the user running bgpd.
