CVE-2022-4988Public exploitNetwork attack vector

Application crashes via outdated bundled libraries

Published May 11, 2026 · Updated May 11, 2026

Bundled-library flaws in KMX Alien::FreeImage 1.001 and earlier allow remote attackers to crash applications that parse crafted images. The bundled FreeImage 3.17.0 code underflows PCX dimensions and lets psdParser::ReadImageData copy an unchecked row size into a bitmap buffer. A consuming application must link the bundled archive and decode attacker-controlled PCX or PSD data, making heap corruption and a process crash the demonstrated consequence.
