Ubuntu 4.10 / 5.04 : tcpdump vulnerability (USN-141-1)
Medium Nessus Plugin ID 20534
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt was discovered that certain invalid BGP packets triggered an infinite loop in tcpdump, which caused tcpdump to stop working. This could be abused by a remote attacker to bypass tcpdump analysis of network traffic.
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.
SolutionUpdate the affected tcpdump package.
