Description Michael Kaplan 2020-08-19 15:33:57 UTC
A buffer overflow vulnerability in p_print_image() in devices/gdevcdj.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

Comment 3 Todd Cullum 2020-08-25 22:23:53 UTC
Flaw summary:

in ep_print_image() of /devices/gdevcdj.c, a missing bounds check in a for loop condition of pointer `p3` could cause an out-of-bounds read when an attacker provides a crafted PDF file to be processed by ghostscript.
