CVE-2008-3655

Keita Yamaguchi discovered that several safe level restrictions are insufficiently enforced.

CVE-2008-3656

Christian Neukirchen discovered that the WebRick module uses inefficient algorithms for HTTP header splitting, resulting in denial of service through resource exhaustion.

CVE-2008-3657

It was discovered that the dl module doesn't perform taintness checks.

CVE-2008-3790

Luka Treiber and Mitja Kolsek discovered that recursively nested XML entities can lead to denial of service through resource exhaustion in rexml.

CVE-2008-3905

Tanaka Akira discovered that the resolv module uses sequential transaction IDs and a fixed source port for DNS queries, which makes it more vulnerable to DNS spoofing attacks.

For the stable distribution (etch), these problems have been fixed in version 1.8.5-4etch3. Packages for arm will be provided later.

For the unstable distribution (sid), these problems have been fixed in version 1.8.7.72-1.

We recommend that you upgrade your ruby1.8 packages.");
