A malicious or compromised RDP server can terminate a connected FreeRDP client after RDPGFX AVC444 negotiation by sending an in-bounds region rectangle with an odd width.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-617"],"vendors":[],"products":[],"references":[{"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-97pf-pwp3-2wrv","tags":[]},{"url":"https://www.vulncheck.com/advisories/freerdp-3.11.0-before-3.32.0-reachable-assertion-via-avc444-odd-region-width","tags":[]}],"exploitRefs":[{"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-97pf-pwp3-2wrv","tags":[]}],"hasPoc":true,"ai":null}
