Description

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.
