Process crash via unchecked sample offsets
Published Apr 13, 2026 · Updated Apr 13, 2026
Out-of-bounds read in ImageMagick 6 before 6.9.13-44 and ImageMagick 7 before 7.1.2-19 allows local users to crash applications. SampleImage in MagickCore/resize.c derives pixel coordinates from sample:offset but previously indexed a fetched scanline with an unchecked computed horizontal offset. Exploitation requires user interaction and an application invocation of -sample with an attacker-controlled offset; the reported consequence is limited to process interruption.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
