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.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - ghostscript: Attempting to open a carefully crafted PDF file results in long-running computation (699856)     (CVE-2018-19478)

  - ghostscript: heap buffer over write vulnerability in GhostScript's lp8000_print_page() in gdevlp8k.c     (CVE-2020-27792)

  - An issue was discovered in the function gdev_prn_open_printer_seekable() in Artifex Ghostscript through     10.02.0 allows remote attackers to crash the application via a dangling pointer. (CVE-2023-46751)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

According to the versions of the ghostscript packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - 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. (CVE-2020-27792)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
