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.

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.
