According to an Internet Security Systems report, a new version of Trin00 is on the loose. The new incarnation runs on Windows-based systems and can be used to coordinate Denial of Service attacks.
The Windows Trin00 variant is similar to its UNIX counterpart. The daemon service with the Windows version listens to port 34555, but it does not attempt to contact a master server.
ISS believes Trin00 is being used in conjunction with BackOrifice and SubSeven to launch attacks. More information is available from ISS.

The CERT Coordination Center is reporting that multiple vulnerabilities exist in the Cron clock daemon software developed by Paul Vixie. Increased hacker activity related to these vulnerabilities prompted CERT to distribute an advisory to UNIX administrators.
Multiple patches and security reports have targeted these vulnerabilities. For a list, and for more information, visit the CERT Coordination Center .
Two holes have been identified in FreeBSD.
The U.S. Department of Energy’s Computer Incident Advisory Capability site is warning that the third-party Delegate Proxy Server software may permit hackers to execute arbitrary code. There are no patches currently available. More information can be found on the CIAC site.
A pair of vulnerabilities has also been discovered in the asmon and ascpu utilities published by Afterstep. These holes could also allow hackers to execute arbitrary code, according to CIAC. Upgrading the software can eliminate the security risk, which CIAC rates as low. More details are available here .
