The remote host has a library installed that is affected by an information disclosure vulnerability.


The remote host is running a version of IBM Tivoli Directory Server and a version of IBM Global Security Kit (GSKit) that is affected by an information disclosure vulnerability. The Transport Layer Security (TLS) protocol does not properly consider timing side-channel attacks, which allows remote attackers to conduct distinguishing attacks and plain-text recovery attacks via statistical analysis of timing data for crafted packets. This type of exploitation is known as the 'Lucky Thirteen' attack.

Alternatively, upgrade GSKit to or or later.
