Description Tomas Hoger 2008-04-09 14:51:54 UTC 
Thomas Pollet reported an integer overflows leading to a heap overflow in the
CUPS' image filter:

  http://www.cups.org/str.php?L2790

  filter/image-png.c:

  img->xsize * img->ysize may overflow (CUPS_IMAGE_MAX_WIDTH and
  CUPS_IMAGE_MAX_HEIGHT are too big for multiplication).

  malloc(img->xsize * img->ysize * 3) can result in a buffer that's too small.

Upstream patch: http://www.cups.org/strfiles/2790/str2790.patch
Comment 4 Tomas Hoger 2008-04-11 07:00:03 UTC 
CVE-2008-1722:

Multiple integer overflows in (1) filter/image-png.c and (2)
filter/image-zoom.c in CUPS 1.3 allow attackers to cause a denial of
service (crash) and trigger memory corruption, as demonstrated via a
crafted PNG image.
Comment 6 Josh Bressers 2008-04-16 14:41:39 UTC 
This issue affects Red Hat Enterprise Linux 3, 4, and 5.
Comment 15 Tomas Hoger 2008-04-23 07:21:29 UTC 
As for vector (2) - image-zoom.c - is not an issue, according to upstream analysis:

CUPS_IMAGE_MAX_WIDTH is 2^27-1, so it is impossible to overflow on
32-bit systems.
