Ubuntu 4.10 / 5.04 / 5.10 : ruby1.8 vulnerability (USN-273-1)

medium Nessus Plugin ID 21292

Synopsis

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

Description

Yukihiro 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.

Solution

Update the affected packages.
