(RHSA-2010:0945) Moderate: quagga security update

Description

Quagga is a TCP/IP based routing software suite. The Quagga bgpd daemon implements the BGP (Border Gateway Protocol) routing protocol. A stack-based buffer overflow flaw was found in the way the Quagga bgpd daemon processed certain BGP Route Refresh (RR) messages. A configured BGP peer could send a specially-crafted BGP message, causing bgpd on a target system to crash or, possibly, execute arbitrary code with the privileges of the user running bgpd. (CVE-2010-2948) Note: On Red Hat Enterprise Linux 6 it is not possible to exploit CVE-2010-2948 to run arbitrary code as the overflow is blocked by FORTIFY_SOURCE. A NULL pointer dereference flaw was found in the way the Quagga bgpd daemon parsed the paths of autonomous systems (AS). A configured BGP peer could crash bgpd on a target system via a specially-crafted BGP message. (CVE-2010-2949) Users of quagga should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the bgpd daemon must be restarted for the update to take effect.
