Security Issue Information

The cPanel security team and independent security researchers
identified the resolved security issues. There is no reason to believe
that these vulnerabilities have been made known to the public. As such,
cPanel will only release limited information about the vulnerabilities
at this time.

Once sufficient time has passed, allowing cPanel & WHM systems to
automatically update to the new versions, cPanel will release
additional information about the nature of the security issues. This
Targeted Security Release addresses 5 vulnerabilities in cPanel & WHM
software versions 11.39, 11.38, 11.36, 11.34, and 11.32.

Additional information is scheduled for release on July 17th, 2013.
