CVE-2026-33855

Service interruption via wrapped CGATS allocation

Published Mar 24, 2026 · Updated Mar 24, 2026

Integer overflow in Android-ImageMagick7 before 7.1.2-11 allows local users to interrupt image processing via a crafted CGATS file. AllocateDataSet in liblcms2-2.9/src/cmscgats.c multiplies attacker-controlled field and set counts without bounds checks, allowing the allocation size to wrap before SetData writes beyond the heap buffer. Exploitation requires an Android app to open the file with user interaction; published sources do not distinguish a crash from another form of service interruption.
