Description

Riku Hietamaki, Tuomo Untinen and Jukka Taimisto discovered that Quagga incorrectly handled Link State Update messages with invalid lengths. A remote attacker could use this flaw to cause Quagga to crash, resulting in a denial of service. (CVE-2011-3323)

Riku Hietamaki, Tuomo Untinen and Jukka Taimisto discovered that Quagga incorrectly handled certain IPv6 Database Description messages. A remote attacker could use this flaw to cause Quagga to crash, resulting in a denial of service. (CVE-2011-3324)

Riku Hietamaki, Tuomo Untinen and Jukka Taimisto discovered that Quagga incorrectly handled certain IPv4 packets. A remote attacker could use this flaw to cause Quagga to crash, resulting in a denial of service. (CVE-2011-3325)

Riku Hietamaki, Tuomo Untinen and Jukka Taimisto discovered that Quagga incorrectly handled invalid Link State Advertisement (LSA) types. A remote attacker could use this flaw to cause Quagga to crash, resulting in a denial of service. (CVE-2011-3326)

Riku Hietamaki, Tuomo Untinen and Jukka Taimisto discovered that Quagga incorrectly handled certain BGP UPDATE messages. A remote attacker could use this flaw to cause Quagga to crash, or possibly execute arbitrary code. (CVE-2011-3327).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
