Description Jan Lieskovsky 2012-06-22 15:47:15 UTC 
A denial of service flaw was found in the way GIMP, GNU Image Manipulation Program, processed certain FIT format files. A remote attacker could provide a FIT format file with specially-crafted value of the 'XTENSION' header that, when opened would cause the gimp executable to crash.

Created gimp tracking bugs for this issue

Affects: fedora-all [bug 836517]

Statement:

We do not consider a user-assisted crash of a client application such as Gimp to be a security issue.
