Process crash via overflowing XCF tile bound
Published Jul 1, 2026 · Updated Jul 1, 2026
Integer overflow in ImageMagick's XCF decoder before 6.9.13-51 and 7.0.1-0 through 7.1.2-25 allows remote attackers to crash processes. In load_level in coders/xcf.c, a floating-point tile-size expression is cast to MagickOffsetType when a second tile offset is zero, allowing the fallback bound to wrap before the tile read. Processing a crafted XCF image is required; the out-of-bounds read can disclose adjacent memory or terminate the consuming process, with no reported write primitive.

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.
- Affected versionversion=< 6.9.13-51
- Affected versionversion=>= 7.0.1-0, < 7.1.2-26
