Description Dhananjay Arunesh 2019-03-25 10:01:34 UTC
In ImageMagick 7.0.8-35 Q16, there is a stack-based buffer overflow in the function PopHexPixel of coders/ps.c, which allows an attacker to cause a denial of service or code execution via a crafted image file.


Comment 1 Dhananjay Arunesh 2019-03-25 10:01:57 UTC
Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1692301]

Comment 5 Marco Benatto 2019-04-10 14:49:43 UTC

This issue affects the versions of ImageMagick as shipped with Red Hat Enterprise Linux 6 and 7.

Red Hat Enterprise Linux 6 is now in Maintenance Support 2 Phase of the support and maintenance life cycle. This has been rated as having a
security impact of Moderate, and is not currently planned to be addressed in future updates. For additional information, refer to the
Red Hat Enterprise Linux Life Cycle: https://access.redhat.com/support/policy/updates/errata/.

Comment 9 Marco Benatto 2019-04-10 15:54:42 UTC
The WritePSImage() function fails to properly enforce the boundaries of a stack-based buffer when converting an image into a PostScript file. A malicious attacker could create a specially crafted image, which, when converted, could lead to a stack-based buffer overflow and, possibly, execution of arbitrary code. Successful exploitation requires that RLE compression is used.
