When the check is optimised away, a malicious SOAP server can make the client allocate a buffer far smaller than the data it then writes into it, producing a heap buffer overflow.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H","cwes":["CWE-190"],"vendors":[],"products":[],"references":[{"url":"https://github.com/php/php-src/security/advisories/GHSA-cj93-vc83-wgqv","tags":[]},{"url":"https://github.com/php/php-src/security/advisories/GHSA-cj93-vc83-wgqv","tags":[]}],"exploitRefs":[{"url":"https://github.com/php/php-src/security/advisories/GHSA-cj93-vc83-wgqv","tags":[]},{"url":"https://github.com/php/php-src/security/advisories/GHSA-cj93-vc83-wgqv","tags":[]}],"hasPoc":true,"ai":null}
