The function value_from_inheritable_property() in css-apply.c recurses through the CSS property inheritance chain without a depth limit, exhausting the process stack and causing a crash in any application using MuPDF for EPUB rendering.","epss":{"date":"2026-11-08","percentile":0.48153,"score":0.00583},"exploits":[{"kind":"exploit","source":"CNA: VulnCheck","url":"https://bugs.ghostscript.com/show_bug.cgi?id=708840"}],"kev":null,"metrics":[{"score":7.1,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":6.5,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1794146432363,"publishedAt":1782235308562,"references":[{"source":"CNA: VulnCheck","tags":["release-notes"],"url":"https://github.com/ArtifexSoftware/mupdf/releases/tag/1.27.0-rc1"},{"source":"CNA: VulnCheck","tags":["technical-description","exploit"],"url":"https://bugs.ghostscript.com/show_bug.cgi?id=708840"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/ArtifexSoftware/mupdf/commit/70b71ab22e6de4d4c44cd301c88231f623a4e94e"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/mupdf-rc1-stack-exhaustion-dos-via-epub-css-rendering"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
