CVSS: 7.1EPSS: 0%CPEs: 2EXPL: 1CVE-2020-27792 – Ghostscript: heap buffer over write vulnerability in ghostscript's lp8000_print_page() in gdevlp8k.c
https://notcve.org/view.php?id=CVE-2020-27792
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. Se encontró una vulnerabilidad de escritura excesiva en el búfer en la región heap de la memoria en la función lp8000_print_page() de GhostScript en el archivo gdevlp8k.c. Un atacante podría engañar a un usuario para que abriera un archivo PDF diseñado, desencadenando el desbordamiento del búfer de la pila que podría conllevar la corrupción de la memoria o una denegación de servicio. • https://access.redhat.com/security/cve/CVE-2020-27792 https://bugs.ghostscript.com/show_bug.cgi?id=701844 https://bugzilla.redhat.com/show_bug.cgi?id=2247179 https://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=4f6bc662909ab79e8fbe9822afb36e8a0eafc2b7 https://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=4f6bc662909ab79e8fbe9822afb36e8a0eafc2b7 https://lists.debian.org/debian-lts-announce/2022/09/msg00005.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

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 •
