CVE-2026-30929

A flaw was found in ImageMagick. Processing a specially crafted image with the MagnifyImage function can cause a stack-based buffer overflow and memory corruption, leading to a denial of service and potentially arbitrary code execution.

To exploit this issue, an attacker needs to convince a user to process a specially crafted image.

Default Red Hat Enterprise Linux security features, including SELinux enforcement, Address Space Layout Randomization (ASLR) and NX (No-Execute) stack protection, significantly increase the difficulty of achieving arbitrary code execution, limiting the impact of this vulnerability to a denial of service.

Due to these reasons, this vulnerability has been rated with a moderate severity.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
