These are all security issues fixed in the ghostscript-10.05.1-1.1 package on the GA media of openSUSE Tumbleweed.

This update for ghostscript fixes the following issues:

Update to version 10.06.0.

Security issues fixed:

• CVE-2025-59800: an integer overflow can lead to a heap-based buffer overflow in ocr_line8 (bsc#1250355).
• CVE-2025-59799: a large size value can cause a stack-based buffer overflow in pdfmark_coerce_dest (bsc#1250354).
• CVE-2025-59798: stack-based buffer overflow in pdf_write_cmap can lead to a denial-of-service (bsc#1250353).
• CVE-2025-48708: lacks of argument sanitization may lead to password disclosure (bsc#1243701).
• CVE-2025-46646: mishandling of overlong utf-8 encoding in artifex ghostscript's decode_utf8 function (bsc#1257699).

Other updates and bugfixes:

• switch over to libalternatives for ghostscript to provide a gs variant (bsc#1245896)

• Version upgrade to 10.06.0:

  • removes the non-standard operator "selectdevice" (cf. the entry below dated Tue Apr 1 09:56:06 UTC 2025)

• Version upgrade to 10.05.1:

  • an overflow issue in Freetype on platforms where long is a 4 byte (rather than 8 byte) type (Microsoft Windows, for example) causing corrupted glyph rendering at higher resolutions
  • an issue with embedded files, affecting Zugferd format PDF creation.
  • broken logic in PDF Optional Content processing
  • potential slow down due to searching for identifiable font files
  • a small number of extreme edge case segmentation faults.

It was discovered that Ghostscript incorrectly handled parsing certain PS files. An attacker could use this issue to cause Ghostscript to crash, resulting in a denial of service, or possibly bypass file path validation.
