Details

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 6.10

• libruby1.8 - 1.8.4-5ubuntu1.2

Ubuntu 6.06

• libruby1.8 - 1.8.4-1ubuntu1.3

In general, a standard system upgrade is sufficient to effect the
necessary changes.
