Hi,
there is just another CVE id for exiftags:
CVE-2007-6354[0]:
| Unspecified vulnerability in exiftags before 1.01 has 
| unknown impact and attack vectors, resulting from a "field 
| offset overflow," a different vulnerability than 
| CVE-2007-6355.

Please check back with upstream for the difference to 
CVE-2007-6355. I had a quick look at the source changes and 
its not obvious what the difference should be.

Hi,
I intend to upload a 0-day NMU for this.
Patch is attached. Unfortunately this NMU will update to the 
newest upstream version. I am not really comfortable with 
this but I have several reasons to do so.

The maintainer is MIA but the package is not orphaned, the 
upstream author is not really responsive in providing 
patches, there is no patch available and without having a 
deep knowledge of what the code does it is also not really 
possible to extract one out of the diff between the 
versions and writing one from scratch seems to be not 
possible for the same reason.

Patch attached.

Kind regards
Nico

Ok because this is rather intrusive I uploaded it to 3-day 
DELAYED now.
Kind regards
