Attackers can send a training PDU then close the channel so the playback thread reads the freed callback in rdpsnd_virtual_channel_write, crashing the client.","cvssScore":5.9,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-362"],"vendors":[],"products":[],"references":[{"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-cx9c-q4jc-wm6c","tags":[]},{"url":"https://www.vulncheck.com/advisories/freerdp-before-3.32.2-use-after-free-via-dynamic-rdpsnd-channel-close","tags":[]},{"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-cx9c-q4jc-wm6c","tags":[]}],"exploitRefs":[{"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-cx9c-q4jc-wm6c","tags":[]},{"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-cx9c-q4jc-wm6c","tags":[]}],"hasPoc":true,"ai":null}
