Debian Security Advisory 2197-1
Posted Mar 21, 2011
Authored by Debian | Site debian.org

Debian Linux Security Advisory 2197-1 - It has been discovered that the Quagga routing daemon contains two denial-of-service vulnerabilities in its BGP implementation. A crafted Extended Communities attribute triggers a null pointer dereference which causes the BGP daemon to crash. The BGP daemon resets BGP sessions when it encounters malformed AS_PATHLIMIT attributes, introducing a distributed BGP session reset vulnerability which disrupts packet forwarding.
