Synopsis ========
Multiple vulnerabilities were found in Quagga, the worst of which leading to remote execution of arbitrary code.
Background ==========
Quagga is a free routing daemon replacing Zebra supporting RIP, OSPF and BGP.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/quagga < 0.99.20 >= 0.99.20
Description ===========
Multiple vulnerabilities have been discovered in Quagga. Please review the CVE identifiers referenced below for details.
Impact ======
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 of the daemon and disruption of IPv4 routing, two errors in ospf6d and ospfd can each be exploited to crash the daemon and disrupt IP routing.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Quagga users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/quagga-0.99.20 "
