Ubuntu 5.10 / 6.06 LTS / 6.10 : ruby1.8 vulnerability (USN-394-1)

medium Nessus Plugin ID 27980

Synopsis

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

Description

An error was found in Ruby's CGI library that did not correctly quote the boundary of multipart MIME requests. Using a crafted HTTP request, a remote user could cause a denial of service, where Ruby CGI applications would end up in a loop, monopolizing a CPU.

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.
