CVE-2025-55298 (GCVE-0-2025-55298)
Vulnerability from cvelistv5
Published
2025-08-26 17:20
Modified
2025-08-26 20:36
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
CWE
  • CWE-123 - Write-what-where Condition
  • CWE-134 - Use of Externally-Controlled Format String
Summary
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to ImageMagick versions 6.9.13-28 and 7.1.2-2, a format string bug vulnerability exists in InterpretImageFilename function where user input is directly passed to FormatLocaleString without proper sanitization. An attacker can overwrite arbitrary memory regions, enabling a wide range of attacks from heap overflow to remote code execution. This issue has been patched in versions 6.9.13-28 and 7.1.2-2.
