CVE-2022-2085

https://notcve.org/view.php?id=CVE-2022-2085

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. Se ha encontrado una vulnerabilidad de desreferencia de puntero NULL en Ghostscript, que es producida cuando trata de representar un gran número de bits en la memoria. • http://git.ghostscript.com/?p=ghostpdl.git%3Bh=ae1061d948d88667bdf51d47d918c4684d0f67df https://bugs.ghostscript.com/show_bug.cgi?id=704945 https://bugzilla.redhat.com/show_bug.cgi?id=2095261 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ERSZX5LKDWAHZWJYBMP2E2UHOPUCDEGV https://security.gentoo.org/glsa/202211-11 https://security.gentoo.org/glsa/202309-03 • CWE-476: NULL Pointer Dereference •
