Ubuntu 4.10 / 5.04 : tcpdump vulnerabilities (USN-119-1)

Medium Nessus Plugin ID 20507


The remote Ubuntu host is missing a security-related patch.


It was discovered that certain invalid GRE, LDP, BGP, and RSVP packets triggered infinite loops 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.


Update the affected tcpdump package.
