Synopsis
The remote CentOS host is missing one or more security updates.Description
Updated quagga packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
Quagga is a TCP/IP based routing software suite. The Quagga bgpd daemon implements the BGP (Border Gateway Protocol) routing protocol.
The Quagga ospfd and ospf6d daemons implement the OSPF (Open Shortest Path First) routing protocol.
A heap-based buffer overflow flaw was found in the way the bgpd daemon processed malformed Extended Communities path attributes. An attacker 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. The UPDATE message would have to arrive from an explicitly configured BGP peer, but could have originated elsewhere in the BGP network. (CVE-2011-3327)
A stack-based buffer overflow flaw was found in the way the ospf6d daemon processed malformed Link State Update packets. An OSPF router could use this flaw to crash ospf6d on an adjacent router.
(CVE-2011-3323)
A flaw was found in the way the ospf6d daemon processed malformed link state advertisements. An OSPF neighbor could use this flaw to crash ospf6d on a target system. (CVE-2011-3324)
A flaw was found in the way the ospfd daemon processed malformed Hello packets. An OSPF neighbor could use this flaw to crash ospfd on a target system. (CVE-2011-3325)
A flaw was found in the way the ospfd daemon processed malformed link state advertisements. An OSPF router in the autonomous system could use this flaw to crash ospfd on a target system. (CVE-2011-3326)
An assertion failure was found in the way the ospfd daemon processed certain Link State Update packets. An OSPF router could use this flaw to cause ospfd on an adjacent router to abort. (CVE-2012-0249)
A buffer overflow flaw was found in the way the ospfd daemon processed certain Link State Update packets. An OSPF router could use this flaw to crash ospfd on an adjacent router. (CVE-2012-0250)
Two flaws were found in the way the bgpd daemon processed certain BGP OPEN messages. A configured BGP peer could cause bgpd on a target system to abort via a specially crafted BGP OPEN message.
