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. References: http://git.ghostscript.com/?p=ghostpdl.git;h=93cb0c0adbd9bcfefd021d59c472388f67d3300d https://bugs.ghostscript.com/show_bug.cgi?id=701786
Created ghostscript tracking bugs for this issue: Affects: fedora-all [bug 1870150]
Flaw summary: 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.
