GHSA-377p-xr9w-8773
ImageMagick versions before 7.1.2-18 have a memory leak vulnerability in the META reader when processing APP1JPEG input paths. This flaw allows attackers to cause a denial of service by exhausting system resources through specially crafted APP1JPEG image files. The vulnerability is categorized as CWE-401 (memory leak).
AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-56366 affects ImageMagick prior to version 7.1.2-18. It involves a memory leak in the META reader component when handling APP1JPEG input paths. An attacker can exploit this by supplying maliciously crafted APP1JPEG images, which trigger the memory leak and lead to resource exhaustion, resulting in denial of service conditions. There is no information on known exploits in the wild. The CVSS 4.0 vector indicates a local attack vector with low complexity and no privileges required, but user interaction is needed. The severity is assessed as moderate.
Potential Impact
Successful exploitation results in a denial of service due to resource exhaustion caused by a memory leak. This can disrupt availability of services relying on vulnerable ImageMagick versions when processing crafted APP1JPEG images.
Mitigation Recommendations
A fix is available in ImageMagick version 7.1.2-18 and later. Users should upgrade to version 7.1.2-18 or newer to remediate this vulnerability. Patch status is not explicitly confirmed in the provided data, but the description indicates the vulnerability is fixed starting with 7.1.2-18. No additional mitigations are specified.
