A buffer overflow vulnerability in jetp3852_print_page() in devices/gdev3852.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.
Created ghostscript tracking bugs for this issue:
Affects: fedora-all [bug 1870150]
In the driver /devices/gdev3852.c, a high resolution file could overflow the stack buffer because there was no check for size in jetp3852_print_page(), resulting in denial of service. The patch ensures that if the scanline size is larger than the buffer, it will error out instead of overflow the stack.
