7.8 - High
- June 25, 2023
Artifex Ghostscript through 10.01.2 mishandles permission validation for pipe devices (with the %pipe% prefix or the | pipe character prefix).
In Artifex Ghostscript through 10.01.0
CVE-2023-28879
9.8 - Critical
- March 31, 2023
In Artifex Ghostscript through 10.01.0, there is a buffer overflow leading to potential corruption of data internal to the PostScript interpreter, in base/sbcp.c. This affects BCPEncode, BCPDecode, TBCPEncode, and TBCPDecode. If the write buffer is filled to one byte less than full, and one then tries to write an escaped character, two bytes are written.
Memory Corruption
A heap-based buffer overwrite vulnerability was found in GhostScript's lp8000_print_page() function in the gdevlp8k.c file
CVE-2020-27792
7.1 - High
- August 19, 2022
A heap-based buffer overwrite vulnerability was found in GhostScript's lp8000_print_page() function in the gdevlp8k.c file. This flaw allows an attacker to trick a user into opening 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
Artifex Ghostscript through 9.26 mishandles .completefont
CVE-2019-25059
7.8 - High
- April 25, 2022

This only affects ghostscript 9.07 as shipped with Red Hat Enterprise Linux 7.

CVE-2018-16802
7.8 - High
- September 10, 2018
An issue was discovered in Artifex Ghostscript before 9.25.

An issue was discovered in Artifex Ghostscript before 9.24
CVE-2018-16585
7.8 - High
- September 06, 2018
An issue was discovered in Artifex Ghostscript before 9.24.
