Package: zziplib
Severity: grave
Tags: security
Justification: user security hole

Hi

The following CVE[0] has be issued against zziplib.
The text says:

Stack-based buffer overflow in the zzip_open_shared_io function in
zzip/file.c in ZZIPlib Library before 0.13.49 allows user-assisted
remote attackers to cause a denial of service (application crash) or
execute arbitrary code via a long filename.

Can you please investigate, if the debian versions are affected or not?
If you do an upload, which fixes this issue, please mention the CVE
number in the changelog.
Thanks for your efforts

Cheers
Steffen

 Hi
 
 The following CVE[0] has be issued against zziplib.

  This seems to be a low-risk, from the one page I found describing
 it:

 
http://www.securitylab.ru/forum/read.php?FID=21TID=40858MID=326187#message326187

  Basically zzcat $longfilename crashes.  I wouldn't have thought
 this would require a DSA.

Yes you are right, although I understood the CVE text in a different way. I 
will downgrade the bug to normal.
Thanks for pointing it out.
