Lifecycle Timeline
5Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Versions prior to 7.1.2-0 and 6.9.13-26 have a heap buffer overflow in the `InterpretImageFilename` function. The issue stems from an off-by-one error that causes out-of-bounds memory access when processing format strings containing consecutive percent signs (`%%`). Versions 7.1.2-0 and 6.9.13-26 fix the issue.
Analysis
ImageMagick is free and open-source software used for editing and manipulating digital images.

Versions 7.1.2-0 and 6.9.13-26 fix the issue.
Technical Context
An out-of-bounds memory access occurs when code reads from or writes to memory locations outside the intended buffer boundaries. This vulnerability is classified as Out-of-bounds Read (CWE-125).
Affected Products
Affected products: Imagemagick Imagemagick
Remediation
Implement proper bounds checking on all array and buffer accesses. Use memory-safe languages or static analysis tools to detect OOB issues.
