Unauthenticated remote attackers can supply a crafted ICO image to corrupt adjacent heap chunk metadata, triggering a glibc abort that crashes the worker.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-787"],"vendors":[],"products":[],"references":[{"url":"https://github.com/imgproxy/imgproxy/security/advisories/GHSA-494m-4556-wf5p","tags":[]},{"url":"https://www.vulncheck.com/advisories/imgproxy-before-4.0.17-out-of-bounds-write-in-ico-loader","tags":[]}],"exploitRefs":[{"url":"https://github.com/imgproxy/imgproxy/security/advisories/GHSA-494m-4556-wf5p","tags":[]}],"hasPoc":true,"ai":null}
