NVD · CVE.org

AnyDesk before 8.0.3 allows unauthenticated remote attackers to execute arbitrary code via a heap-based buffer overflow, as demonstrated on Linux for command execution as root without the victim approving desktop control. In the stream packet handler for mode 5 in the session protocol, a payload length value is not validated.
