Ubuntu 4.10 / 5.04 / 5.10 : ruby1.8 vulnerability (USN-273-1)
Medium Nessus Plugin ID 21292
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionYukihiro Matsumoto reported that Ruby's HTTP module uses blocking sockets. By sending large amounts of data to a server application that uses this module, a remote attacker could exploit this to render this application unusable and not respond any more to other clients (Denial of Service).
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 packages.
