Doc Text:
A flaw was found in FreeImage. This vulnerability allows an attacker to achieve arbitrary code execution or cause an application crash leading to a Denial of Service (DoS) by tricking a user or automated system into processing a specially crafted image file. The issue occurs due to a heap-based buffer overflow in the image decoder, where missing boundary checks allow data to be written beyond allocated memory limits.

Description OSIDB Bzimport 2026-10-28 21:25:50 UTC
FreeImage (danoli3 fork) before 3.19.22 contains 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.
