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.Show less

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.Show less

A vulnerability classified as problematic was found in GhostPCL 9.55.0. This vulnerability affects the function chunk_free_object of the file gsmchunk.c. The manipulation with a malicious file leads to a memory corruption. The attack can be initiated remotely but requires user interaction. The exploit has been disclosed to the public as a POC and may be used. It is recommended to apply the patches to fix this issue.Show less

A trivial sandbox (enabled with the `-dSAFER` option) escape flaw was found in the ghostscript interpreter by injecting a specially crafted pipe command. This flaw allows a specially crafted document to execute arbitrary commands on the system in the context of the ghostscript interpreter. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.Show less

A Use After Free vulnerability exists in Artifex Software, Inc. MuPDF library 1.17.0-rc1 and earlier when a valid page was followed by a page with invalid pixmap dimensions, causing bander - a static - to point to previously freed memory instead of a newband_writer.Show less
