Mandriva Linux Security Advisory 2010-174

Posted Sep 11, 2010

Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2010-174 - Stack-based buffer overflow in the bgp_route_refresh_receive function in bgp_packet.c in bgpd in Quagga before 0.99.17 allows remote authenticated users to cause a denial of service (daemon crash) or possibly execute arbitrary code via a malformed Outbound Route Filtering message. bgpd in Quagga before 0.99.17 does not properly parse AS paths, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an unknown AS type in an AS path attribute in a BGP UPDATE message. Updated packages are available that bring Quagga to version 0.99.17 which provides numerous bugfixes over the previous 0.99.12 version, and also corrects these issues.
