In addition, this security update addresses a regression in the REXML XML parser of the ruby1.8 package, the regression was introduced in DSA-1651-1.

For the stable distribution (etch), this problem has been fixed in version 1.8.5-4etch4 of the ruby1.8 package, and version 1.9.0+20060609-1etch4 of the ruby1.9 package.

For the unstable distribution (sid), this problem has been fixed in version 1.8.7.72-1 of the ruby1.8 package. The ruby1.9 package will be fixed soon.

We recommend that you upgrade your Ruby packages.");
