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.
