A malicious RDP server can send a crafted low-bit-depth PNG clipboard payload that, when pasted by the victim, discloses megabytes of heap memory.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","cwes":["CWE-125"],"vendors":[],"products":[],"references":[{"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-f3vg-h45x-6wgf","tags":[]},{"url":"https://www.vulncheck.com/advisories/vulnerability-in-freerdp","tags":[]}],"exploitRefs":[{"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-f3vg-h45x-6wgf","tags":[]}],"hasPoc":true,"ai":null}
