{"id":"CVE-2026-54633","state":"PUBLISHED","title":"PoDoFo: Heap Out-of-Bounds Read in Indexed Color Space Image Decoding (FetchScanLine)","description":"PoDoFo is a C++17 PDF manipulation library. From version 1.0.0 until 1.1.1, processing a crafted PDF with an Indexed color-space image can cause a heap out-of-bounds read in PdfColorSpaceFilterIndexed::FetchScanLine in src/podofo/main/PdfColorSpaceFilter.cpp. PODOFO_INVARIANT does not perform a runtime check, so a pixel index greater than or equal to m_MapSize can address beyond m_lookup. PdfColorSpaceFilterFactory::TryCreateFromObject also validates hival with an incorrect conjunction and no upper bound, allowing malformed Indexed color-space metadata outside the expected range. The resulting read can disclose adjacent heap data or crash the processing application. This issue is fixed in version 1.1.1.","publishedAt":"2026-09-17T21:36:45.592Z","updatedAt":"2026-09-22T01:52:46.723Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["podofo podofo"],"affected":[{"vendor":"podofo","product":"podofo","versions":[{"version":">= 1.0.0, < 1.1.1","status":"affected"}]}],"references":["https://github.com/podofo/podofo/security/advisories/GHSA-f3j2-7846-h5gg","https://github.com/podofo/podofo/commit/999c519d285c4a65eba48409d9cd2da9d4743cca","https://github.com/podofo/podofo/releases/tag/1.1.1"],"weaknesses":["CWE-125"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/54xxx/CVE-2026-54633.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-54633","state":"PUBLISHED","datePublished":"2026-09-17T21:36:45.592Z","dateUpdated":"2026-09-22T01:52:46.723Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-15T20:07:02.185Z"},"containers":{"cna":{"title":"PoDoFo: Heap Out-of-Bounds Read in Indexed Color Space Image Decoding (FetchScanLine)","descriptions":[{"lang":"en","value":"PoDoFo is a C++17 PDF manipulation library.
