Red Hat Product Errata RHSA-2012:1259 0 normal SHIPPED_LIVE Moderate: quagga security update 2012-09-13 00:00:43 UTC

Description Jan Lieskovsky 2012-04-30 14:39:21 UTC 
A denial of service flaw was found in the way Quagga's bgpd daemon processed certain OPEN messages. A configured Border Gateway Protocol (BGP) peer could send a BGP OPEN message with specially-crafted value of the Outbound Route Filtering (ORF) capability Type/Length/Value (TLV) triplet, which would cause the master BGP daemon (bgpd) to abort with an assertion failure by processing of such a message. Also, all BGP sessions established by the attacked router would be closed and its BGP routing disrupted.
