It was discovered that Quagga incorrectly parsed certain malformed extended communities. A remote attacker could use this flaw to cause Quagga to crash, resulting in a denial of service. (CVE-2010-1674)

It was discovered that Quagga resets BGP sessions when encountering malformed AS_PATHLIMIT attributes. A remote attacker could use this flaw to disrupt BGP sessions, resulting in a denial of service. This update removes AS_PATHLIMIT support from Quagga. This issue only affected Ubuntu 8.04 LTS, 9.10, 10.04 LTS and 10.10. (CVE-2010-1675).

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.
