+title: Dangling pointer in RDP static virtual channel handling
+cve:   CVE-2020-9498
+fixed: 1.2.0
+---
+
+Apache Guacamole 1.1.0 and older may mishandle pointers involved in processing
+data received via RDP static virtual channels. If a user connects to a
+malicious or compromised RDP server, a series of specially-crafted PDUs could
+result in memory corruption, possibly allowing arbitrary code to be executed
+with the privileges of the running guacd process.
