Multiple vulnerabilities were found in Quagga, the worst of which
leading to remote execution of arbitrary code.
Quagga is a free routing daemon replacing Zebra supporting RIP, OSPF and
Multiple vulnerabilities have been discovered in Quagga. Please review
the CVE identifiers referenced below for details.
A BGP peer could send a Route-Refresh message with specially-crafted ORF
record, which can cause Quagga's bgpd to crash or possibly execute
arbitrary code with the privileges of the user running Quagga's bgpd; a
BGP update AS path request with unknown AS type, or malformed
AS-Pathlimit or Extended-Community attributes could lead to Denial of
Service (daemon crash), an error in bgpd when handling AS_PATH attributes
within UPDATE messages can
be exploited to cause a heap-based buffer overflow resulting in a crash
daemon and disruption of IPv4 routing, two errors in ospf6d and ospfd can
each be exploited to crash the daemon and disrupt IP routing.
There is no known workaround at this time.
All Quagga users should upgrade to the latest version:
