Service interruption via excessive aligned-memory allocation
Published Jun 10, 2026 · Updated Jun 10, 2026
Uncontrolled memory allocation in ImageMagick 6 before 6.9.13-50 and 7 before 7.1.2-25 allows remote attackers to exhaust memory and stop service. AcquireAlignedMemory calculates the requested size but omits a GetMaxMemoryRequest limit check, so it accepts an excessive aligned allocation. No triggering image operation or input path is disclosed; exploitation requires an application to process attacker-controlled input, with no reported data exposure or modification.
