Description David Walser 2015-05-13 16:18:55 CEST 
+++ This bug was initially created as a clone of Bug #15910 +++

An advisory has been issued today (May 11):
http://www.ocert.org/advisories/ocert-2015-006.html

Patched packages uploaded for Mageia 4 and Cauldron.

Advisory:
========================

Updated dcraw and ufraw packages fix security vulnerability:

The dcraw tool suffers from an integer overflow condition which lead to a
buffer overflow. The vulnerability concerns the 'len' variable, parsed without
validation from opened images, used in the ljpeg_start() function. A
maliciously crafted raw image file can be used to trigger the vulnerability,
causing a Denial of Service condition (CVE-2015-3885).

The ufraw package also contains the affected code.  The dcraw and ufraw
packages have been patched to fix this issue.

Comment 1 claire robinson 2015-05-13 16:46:26 CEST 
Can be tested by opening various raw type images.

eg.

$ ufraw

opens a file chooser dialogue and displays the images chosen.

$ dcraw -i *.CR2 *.NEF
_MG_8882.CR2 is a Canon EOS 30D image.
RAW_CANON_450D.CR2 is a Canon EOS 450D image.
RAW_NIKON_D100.NEF is a Nikon D100 image.

or with -v to display more image info.
