Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-787 and the CVSS impact.

Summary

FreeImage through 3.18.0 and the danoli3 FreeImage fork before 3.19.22 contain a heap buffer overflow in the PBM RLE decoder of PluginIFF.cpp. The decoder lacks bounds checks on ByteRun1 runs, which allows an out-of-bounds write (CWE-787). A local attacker with no privileges can make a user open a crafted IFF/LBM PBM file that writes up to 127 controlled bytes past the heap-allocated bitmap.
