Sun Microsystems' discontinued set of Cobalt servers have been struck by a second "extremely critical" security hole in as many months.
The latest hole allows for remote system access.
Sun has issued a patch along with other patch fixes for less critical vulnerabilities which could be used to gain higher privileges on a system.
This hole comes on top of another in February. That time another three less-critical patches were released at the same time. In January, yet another "highly critical" hole was found, combined with two others.
None of this looks good for the thousands of companies running Cobalt servers for web hosting and development environments.
Sun chose the Christmas period to announce it would no longer support the Cobalt servers but has vowed to provide support for them for three years.
