EPSS · scored 2026-10-27

ImageMagick before 7.1.2-15 contains a heap-buffer-overflow read vulnerability in GetPixelIndex caused by OpenPixelCache updating image channel metadata before pixel cache memory allocation. Attackers can trigger memory and disk allocation failures to cause a heap-buffer-overflow read affecting any writer calling GetPixelIndex.

  • WID-SEC-W-2026-0484ImageMagick: Mehrere SchwachstellenDeutsch2026-02-23csaf · cert_bundDE

    Ein Angreifer kann mehrere Schwachstellen in ImageMagick ausnutzen, um beliebigen Programmcode auszuführen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, vertrauliche Informationen offenzulegen, einen Denial-of-Service-Zustand herbeizuführen oder andere nicht näher definierte Angriffe durchzuführen.

  • GHSA-gq5v-qf8q-fp77ImageMagick: Heap-based Buffer Overflow in GetPixelIndex due to metadata-cache desynchronization2026-02-25ghsa · osvUS

    `OpenPixelCache` updates image channel metadata **before** attempting pixel cache memory allocation. When both memory and disk allocation fail a heap-buffer-overflow read in occurs in any writer that calls `GetPixelIndex`.
