Cairo through 1.18.4, as used in Poppler through 25.08.0, has an "unscaled->face == NULL" assertion failure for _cairo_ft_unscaled_font_fini in cairo-ft-font.c.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2025:03449-1 advisory.

    - CVE-2025-50422: Fixed Poppler crash on malformed input (bsc#1247589)

    - Update to version 1.18.4:
      - The dependency on LZO has been made optional through a build         time configuration toggle.
      - You can build Cairo against a Freetype installation that does         not have the FT_Color type.
      - Cairo tests now build on Solaris 11.4 with GCC 14.
      - The DirectWrite backend now builds on MINGW 11.
      - The DirectWrite backend now supports font variations and proper         glyph coverage.
    - Use tarball in lieu of source service due to freedesktop gitlab       migration, will switch back at next release at the latest.
    - Add pkgconfig(lzo2) BuildRequires: New optional dependency, build       lzo2 support feature.

    - Convert to source service: allows for easier upgrades by the       GNOME team.

    - Update to version 1.18.2:
      - The malloc-stats code has been removed from the tests directory
      - Cairo now requires a version of pixman equal to, or newer than,         0.40.
      - There have been multiple build fixes for newer versions of GCC         for MSVC; for Solaris; and on macOS 10.7.
      - PNG errors caused by loading malformed data are correctly         propagated to callers, so they can handle the case.
      - Both stroke and fill colors are now set when showing glyphs on         a PDF surface.
      - All the font options are copied when creating a fallback font         object.
      - When drawing text on macOS, Cairo now tries harder to select         the appropriate font name.
      - Cairo now prefers the COLRv1 table inside a font, if one is         available.
      - Cairo requires a C11 toolchain when building.
