Ubuntu 8.04 LTS : linux vulnerability (USN-1660-1)

Medium Nessus Plugin ID 63221


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


Zhang Zuotao discovered a bug in the Linux kernel's handling of overlapping fragments in ipv6. A remote attacker could exploit this flaw to bypass firewalls and initial new network connections that should have been blocked by the firewall.

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 packages.
