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.

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.

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-2024-46956: fix out-of-bounds data access in filenameforall to prevent arbitrary code execution

• SECURITY UPDATE: arbitrary code execution via the opvp Driver parameter
  • debian/patches/CVE-2024-33871.patch: refuse a Driver change once LockSafetyParams is set, and report the Driver length without the trailing NUL, in contrib/opvp/gdevopvp.c.
  • CVE-2024-33871
• SECURITY UPDATE: unchecked Implementation pointer in Pattern colour space
  • debian/patches/CVE-2024-46951.patch: check that the Pattern Implementation object really is a pattern instance before dereferencing it in patterncomponent() in psi/zcolor.c.
  • CVE-2024-46951
• SECURITY UPDATE: integer overflow validating the output filename format
  • debian/patches/CVE-2024-46953.patch: reject format widths that overflow an int and tighten the length check in gx_parse_output_format() and gx_parse_output_file_name() in base/gsdevice.c.
  • CVE-2024-46953
• SECURITY UPDATE: out-of-bounds data access in filenameforall
  • debian/patches/CVE-2024-46956.patch: correct the buffer length check in file_continue() in psi/zfile.c, so filenameforall cannot return a string whose declared size exceeds the scratch buffer.
