Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

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.

Update the affected quagga and / or quagga-doc packages.
