Summaryinfo

A vulnerability described as problematic has been identified in Ghostscript. Affected by this vulnerability is an unknown functionality. Executing a manipulation of the argument init_device_procs can lead to null pointer dereference. This vulnerability is tracked as CVE-2022-2085. No exploit exists. Applying a patch is advised to resolve this issue.

Detailsinfo

A vulnerability classified as problematic was found in Ghostscript (Document Processing Software) (unknown version). This vulnerability affects an unknown code block. The manipulation of the argument init_device_procs with an unknown input leads to a null pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. As an impact it is known to affect availability. CVE summarizes:

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.

The weakness was disclosed 06/17/2022. The advisory is shared for download at git.ghostscript.com. This vulnerability was named CVE-2022-2085 since 06/15/2022. There are known technical details, but no exploit is available.

Applying the patch ae1061d948d88667bdf51d47d918c4684d0f67df is able to eliminate this problem. The bugfix is ready for download at git.ghostscript.com.
