Unspecified vulnerability in the AClient agent in Symantec Altiris Deployment Solution 6.9.x before 6.9 SP3 Build 430, when key-based authentication is being used between a deployment server and a client, allows remote attackers to bypass authentication and execute arbitrary commands as SYSTEM by spoofing the deployment server and sending "alternate commands" before the handshake is completed.

DBManager in Symantec Altiris Deployment Solution 6.9.x before DS 6.9 SP4 allows remote attackers to cause a denial of service via a crafted request.

Symantec Altiris Deployment Solution 6.9.x before 6.9 SP3 Build 430 does not properly restrict access to the listening port for the DBManager service, which allows remote attackers to bypass authentication and modify tasks or the Altiris Database via a connection to this service.
