An attacker able to induce concurrent security policy access can crash the application, causing a denial of service.","cvssScore":2.5,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L","cwes":["CWE-362"],"vendors":[],"products":[],"references":[{"url":"https://github.com/ImageMagick/ImageMagick/commit/12db6f04e895deae4537ead10c771a244607794a","tags":[]},{"url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-8x3v-wr32-qqh4","tags":[]},{"url":"https://github.com/ImageMagick/ImageMagick6/commit/9ddc71abea5cbe7d18164fa0f0077a105cab514f","tags":[]},{"url":"https://www.vulncheck.com/advisories/imagemagick-before-6.9.13-57-and-7-x-before-7.1.2-32-heap-buffer-overflow-via-concurrent-security-policy-access","tags":[]}],"exploitRefs":[{"url":"https://github.com/ImageMagick/ImageMagick/commit/12db6f04e895deae4537ead10c771a244607794a","tags":[]},{"url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-8x3v-wr32-qqh4","tags":[]},{"url":"https://github.com/ImageMagick/ImageMagick6/commit/9ddc71abea5cbe7d18164fa0f0077a105cab514f","tags":[]}],"hasPoc":true,"ai":null}
