Description Vladimir Vasilev 2026-09-23 11:15:03 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
