Recent Artifex Ghostscript Security Vulnerabilities

A heap-based buffer over write vulnerability was found in GhostScript's lp8000_print_page() function in gdevlp8k.c file

CVE-2020-27792 7.1 - High - August 19, 2022

A heap-based buffer over write vulnerability was found in GhostScript's lp8000_print_page() function in gdevlp8k.c file. An attacker could trick a user to open a crafted PDF file, triggering the heap buffer overflow that could lead to memory corruption or a denial of service.

Buffer Overflow

A NULL pointer dereference vulnerability was found in Ghostscript, which occurs when it tries to render a large number of bits in memory

CVE-2022-2085 5.5 - Medium - June 16, 2022

A NULL pointer dereference vulnerability was found in Ghostscript, which occurs when it tries to render a large number of bits in memory. When allocating a buffer device, it relies on an init_device_procs defined for the device that uses it as a prototype that depends upon the number of bits per pixel. For bpp > 64, mem_x_device is used and does not have an init_device_procs defined. This flaw allows an attacker to parse a large number of bits (more than 64 bits per pixel), which triggers a NULL pointer dereference flaw, causing an application to crash.

NULL Pointer Dereference
