Summary

The remote host is missing an update for the 'quagga' package(s) announced via the referenced advisory.

Insight

Insight

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 5 it is not possible to exploit CVE-2010-2948 to run arbitrary code as the overflow is blocked by FORTIFY_SOURCE. Multiple NULL pointer dereference flaws were found in the way the Quagga bgpd daemon processed certain specially-crafted BGP messages. A configured BGP peer could crash bgpd on a target system via specially-crafted BGP messages. (CVE-2007-4826) 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.
