Description

Sun Solaris has been found vulnerable to a privilege escalation vulnerability in "dtsession".

dtsession is installed setuid "root" and does not properly verify the "HOME" environment variable. This allows a malicious user to cause a heap overflow which can be exploited to execute arbitrary code with root privileges.


Solution
It is necessary to remove the setuid bit until Sun issues a patch. This may prevent users from unlocking the screen.
