Symantec pcAnywhere through 12.5.3, Altiris IT Management Suite pcAnywhere Solution 7.0 (aka 12.5.x) and 7.1 (aka 12.6.x), Altiris Client Management Suite pcAnywhere Solution 7.0 (aka 12.5.x) and 7.1 (aka 12.6.x), and Altiris Deployment Solution Remote pcAnywhere Solution 7.1 (aka 12.5.x and 12.6.x) do not properly handle the client state after abnormal termination of a remote session, which allows remote attackers to obtain access to the client by leveraging an "open client session."

Buffer overflow in Symantec pcAnywhere 11.0.1, 11.5.1, and all other 32-bit versions allows remote attackers to cause a denial of service (application crash) via unknown attack vectors.

Symantec pcAnywhere 10.5x and 11.x before 11.5, with "Launch with Windows" enabled, allows local users with physical access to execute arbitrary commands via the Caller Properties feature.

pcAnywhere 8.x and 9.0 allows remote attackers to cause a denial of service via a TCP SYN scan, e.g. by nmap.
