The BGP daemon is vulnerable to a Denial of Service. Background ========= The Quagga Routing Suite implements three major routing protocols: RIP (v1/v2/v3), OSPF (v2/v3) and BGP4. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/quagga < 0.98.6-r1 > = 0.98.6-r1 Description ========== Konstantin V. Gavrilenko discovered two flaws in the Routing Information Protocol (RIP) daemon that allow the processing of RIP v1 packets (carrying no authentication) even when the daemon is configured to use MD5 authentication or, in another case, even if RIP v1 is completely disabled. Additionally, Fredrik Widell reported that the Border Gateway Protocol (BGP) daemon contains a flaw that makes it lock up and use all available CPU when a specific command is issued from the telnet interface. Impact ===== By sending RIP v1 response packets, an unauthenticated attacker can alter the routing table of a router running Quagga's RIP daemon and disclose routinginformation. Additionally, it is possible to lock up the BGP daemon from the telnet interface. 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-0.98.6-r1" References ========= [ 1 ] CVE-2006-2223 https://www.cve.org/CVERecord?id=CVE-2006-2223 [ 2 ] CVE-2006-2224 https://www.cve.org/CVERecord?id=CVE-2006-2224 [ 3 ] CVE-2006-2276 https://www.cve.org/CVERecord?id=CVE-2006-2276 [ 4 ] Official release information ;m=5&d=8#id1147115280 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200605-15 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
