| Descripción: | Summary:
The remote host is missing an update for the 'quagga'
package(s) announced via the referenced advisory.
Vulnerability Insight:
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 NULL pointer dereference flaw was found in the way the bgpd daemon
processed malformed route Extended Communities attributes. A configured
BGP peer could crash bgpd on a target system via a specially-crafted BGP
message. (CVE-2010-1674)
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)
