CVE-2026-118752: FreeImage through 3.18.0 and danoli3 fork before 3.19.22 Heap Buffer Overflow via IFF/LBM PBM RLE Decoder
Noroxi assessment
Priority: Monitor (action score 34/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.15% (FIRST EPSS).
- Someone with local access to the system can trigger it. No account or password is required. No special conditions are required; it is repeatable.
- Fixed version: danoli3 FreeImage 3.19.22.
Low priority for now. Upgrade to danoli3 FreeImage 3.19.22 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
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.
