Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2025-50422 - Priority: Routine - CVSS: 2.9 (Low) - EPSS: 0.0026 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Aug 27, 2025 - Weakness: Reachable Assertion - Vendor advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-50422 ## Description This update for cairo fixes the following issues: - 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. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | cairo amzn 2023 | 1.18.0-4.amzn2023.0.3 | [ALAS2023-2025-1172](https://patchblox.com/security/data/fix/linux/alas2023-2025-1172.md) | Aug 27, 2025 | | Linux | cairo opensuse-leap 15.6 | 1.18.4-150600.3.3.1 | [SUSE-SU-2025:03449-1](https://patchblox.com/security/data/fix/linux/suse-su-2025-03449-1.md) | Oct 2, 2025 | | Linux | cairo sles 15.6 | 1.18.4-150600.3.3.1 | [SUSE-SU-2025:03449-1](https://patchblox.com/security/data/fix/linux/suse-su-2025-03449-1.md) | Oct 2, 2025 | | Linux | cairo sles 15.7 | 1.18.4-150600.3.3.1 | [SUSE-SU-2025:03449-1](https://patchblox.com/security/data/fix/linux/suse-su-2025-03449-1.md) | Oct 2, 2025 | | Linux | cairo-debuginfo amzn 2023 | 1.18.0-4.amzn2023.0.3 | [ALAS2023-2025-1172](https://patchblox.com/security/data/fix/linux/alas2023-2025-1172.md) | Aug 27, 2025 | | Linux | cairo-debugsource amzn 2023 | 1.18.0-4.amzn2023.0.3 | [ALAS2023-2025-1172](https://patchblox.com/security/data/fix/linux/alas2023-2025-1172.md) | Aug 27, 2025 | | Linux | cairo-devel amzn 2023 | 1.18.0-4.amzn2023.0.3 | [ALAS2023-2025-1172](https://patchblox.com/security/data/fix/linux/alas2023-2025-1172.md) | Aug 27, 2025 | | Linux | cairo-gobject amzn 2023 | 1.18.0-4.amzn2023.0.3 | [ALAS2023-2025-1172](https://patchblox.com/security/data/fix/linux/alas2023-2025-1172.md) | Aug 27, 2025 | | Linux | cairo-gobject-debuginfo amzn 2023 | 1.18.0-4.amzn2023.0.3 | [ALAS2023-2025-1172](https://patchblox.com/security/data/fix/linux/alas2023-2025-1172.md) | Aug 27, 2025 | | Linux | cairo-gobject-devel amzn 2023 | 1.18.0-4.amzn2023.0.3 | [ALAS2023-2025-1172](https://patchblox.com/security/data/fix/linux/alas2023-2025-1172.md) | Aug 27, 2025 | | Linux | cairo-tools amzn 2023 | 1.18.0-4.amzn2023.0.3 | [ALAS2023-2025-1172](https://patchblox.com/security/data/fix/linux/alas2023-2025-1172.md) | Aug 27, 2025 | | Linux | cairo-tools-debuginfo amzn 2023 | 1.18.0-4.amzn2023.0.3 | [ALAS2023-2025-1172](https://patchblox.com/security/data/fix/linux/alas2023-2025-1172.md) | Aug 27, 2025 | --- Data as of 2026-11-10T20:03:11Z UTC.
