# CVE-2026-118752: FreeImage through 3.18.0 and danoli3 fork before 3.19.22 Heap Buffer Overflow via IFF/LBM PBM RLE Decoder Status: published. Published: 2026-10-28. Updated: 2026-11-02. FreeImage through 3.18.0 and the danoli3 FreeImage fork before 3.19.22 contain a heap buffer overflow vulnerability in the PBM RLE decoder of PluginIFF.cpp that lacks bounds checks on ByteRun1 runs. Attackers can supply a crafted IFF/LBM PBM file with runs straddling scanline ends to write up to 127 controlled bytes past the heap-allocated bitmap. ## Remediation - fix: The reporting source identifies this reference as a patch.
