Thank you for the additional info and the potential patch.

I have prepared the update for Wheezy based on the upstream patch
instead to diverge less from upstream in case we have to patch the code
further. The error reporting is also more verbose and accurate.

Please see the diff to previous version attached.

Changes:
 dcmtk (3.6.0-12+deb7u1) wheezy-security; urgency=medium
 .
   * LTS Team upload.
   * Fix remote stack buffer overflow (CVE-2015-8979) (Closes: #848830)
   * Enable tests for the fix

I plan uploading the package today around 22:00 UTC.

The binary packages for amd64 are also available for testing here:

Cheers,
Balint
