-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------- Debian Security Advisory DSA-2316-1 security@debian.org http://www.debian.org/security/ Florian Weimer October 05, 2011 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : quagga Vulnerability : several Problem type : remote Debian-specific: no CVE ID : CVE-2011-3323 CVE-2011-3324 CVE-2011-3325 CVE-2011-3326 CVE-2011-3327 Riku Hietamaki, Tuomo Untinen and Jukka Taimisto discovered several vulnerabilities in Quagga, an Internet routing daemon: CVE-2011-3323 A stack-based buffer overflow while decoding Link State Update packets with a malformed Inter Area Prefix LSA can cause the ospf6d process to crash or (potentially) execute arbitrary code. CVE-2011-3324 The ospf6d process can crash while processing a Database Description packet with a crafted Link-State-Advertisement. CVE-2011-3325 The ospfd process can crash while processing a crafted Hello packet. CVE-2011-3326 The ospfd process crashes while processing Link-State-Advertisements of a type not known to Quagga. CVE-2011-3327 A heap-based buffer overflow while processing BGP UPDATE messages containing an Extended Communities path attribute can cause the bgpd process to crash or (potentially) execute arbitrary code. The OSPF-related vulnerabilities require that potential attackers send packets to a vulnerable Quagga router; the packets are not distributed over OSPF. In contrast, the BGP UPDATE messages could be propagated by some routers. For the oldstable distribution (lenny), these problems have been fixed in version 0.99.10-1lenny6. For the stable distribution (squeeze), these problems have been fixed in version 0.99.17-2+squeeze3. For the testing distribution (wheezy) and the unstable distribution (sid), these problems have been fixed in version 0.99.19-1. We recommend that you upgrade your quagga packages.
