Attackers completing the RDG tunnel-open exchange then send an eight-byte header with packetLength 0xFFFF and withhold the body, causing an unbounded no-progress read loop that spins one client thread at full CPU.","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-835"],"vendors":["freerdp"],"products":["freerdp"],"references":[{"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-x4x6-2hrm-hvq9","tags":["Vendor Advisory"]},{"url":"https://www.vulncheck.com/advisories/freerdp-before-3.32.2-cpu-exhaustion-via-rdg-control-packet","tags":["Third Party Advisory"]}],"exploitRefs":[{"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-x4x6-2hrm-hvq9","tags":["Vendor Advisory"]}],"hasPoc":true,"ai":null}
