A malicious RDP client can send two SNDC_FORMATS PDUs with an nBlockAlign too small for nChannels, causing an unbounded heap write during server audio playback, potentially enabling code execution.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-122"],"vendors":[],"products":[],"references":[{"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-3m9q-g533-rqjq","tags":[]},{"url":"https://www.vulncheck.com/advisories/freerdp-before-3.32.1-heap-buffer-overflow-via-rdpsnd-server-select-format","tags":[]}],"exploitRefs":[{"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-3m9q-g533-rqjq","tags":[]}],"hasPoc":true,"ai":null}
