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.

The Aclient GUI in Symantec Altiris Deployment Solution 6.9.x before 6.9 SP3 Build 430 installs a client executable with insecure permissions (Everyone:Full Control), which allows local users to gain privileges by replacing the executable with a Trojan horse program.

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.

Race condition in the file transfer functionality in Symantec Altiris Deployment Solution 6.9.x before 6.9 SP3 Build 430 allows remote attackers to read sensitive files and prevent client updates by connecting to the file transfer port before the expected client does.

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.
