Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
Apache Guacamole 0.9.10 through 1.5.1 may continue to reference a freed RDP audio input buffer. Depending on timing, this may allow an attacker to execute arbitrary code with the privileges of the guacd process.
