ghostscript-9.27-16.el8_10

The Ghostscript suite contains utilities for rendering PostScript and PDF documents. Ghostscript translates PostScript code to common bitmap formats so that the code can be displayed or printed.

Security Fix(es):

* ghostscript: heap buffer over write vulnerability in GhostScript's lp8000_print_page() in gdevlp8k.c (CVE-2020-27792)
* ghostscript: dangling pointer in gdev_prn_open_printer_seekable() (CVE-2023-46751)
* ghostscript: Buffer Overflow in Ghostscript PDF XRef Stream Handling (CVE-2024-46952)
* ghostscript: Arbitrary Code Execution in Artifex Ghostscript Pattern Color Space (CVE-2024-46951)
* ghostscript: Directory Traversal in Ghostscript via Overlong UTF-8 Encoding (CVE-2024-46954)
* ghostscript: Path Traversal and Code Execution via Integer Overflow in Ghostscript (CVE-2024-46953)
* ghostscript: Out-of-Bounds Data Access in Ghostscript Leads to Arbitrary Code Execution (CVE-2024-46956)

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.
CVE-2023-46751
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-2024-46951
An issue was discovered in psi/zcolor.c in Artifex Ghostscript before 10.04.0. An unchecked Implementation pointer in Pattern color space could lead to arbitrary code execution.
CVE-2024-46952
An issue was discovered in pdf/pdf_xref.c in Artifex Ghostscript before 10.04.0. There is a buffer overflow during handling of a PDF XRef stream (related to W array values).
CVE-2024-46953
An issue was discovered in base/gsdevice.c in Artifex Ghostscript before 10.04.0. An integer overflow when parsing the filename format string (for the output filename) results in path truncation, and possible path traversal and code execution.
CVE-2024-46954
An issue was discovered in decode_utf8 in base/gp_utf8.c in Artifex Ghostscript before 10.04.0. Overlong UTF-8 encoding leads to possible ../ directory traversal.
CVE-2024-46956
An issue was discovered in psi/zfile.c in Artifex Ghostscript before 10.04.0. Out-of-bounds data access in filenameforall can lead to arbitrary code execution.
