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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · updated 2026-09-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-54633.json)","depth":"sunlit","depthScore":38,"depthScoreParts":{"impact":38,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
