CVE-2026-118752

FreeImage through 3.18.0 and danoli3 fork before 3.19.22 Heap Buffer Overflow via IFF/LBM PBM RLE Decoder

8.5 High

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.
