Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2010:0785
The remote host is missing updates announced in
advisory RHSA-2010:0785.

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

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.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
