Bug Id
4680913
Date of Resolved Release02-DEC-2003
Impact
On Solaris systems which run the Xsun(1) Solaris X11 server, unprivileged local users may be able to overwrite or create any file on the system due to a security vulnerability involving Xsun(1) and Direct Graphics Access (DGA) mode. Xsun is normally started by "root" user from "dtlogin", and typically has full root privileges. This issue may also allow a local user to crash the Xsun process of any user of a DGA application, a type of "Denial-of-Service".
