New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 5.9

Synopsis

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

Description

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.

Solution

Install the appropriate fix based on the vendor's advisory :

- 6.0.0.72-ISS-ITDS
- 6.1.0.55-ISS-ITDS
- 6.2.0.30-ISS-ITDS
- 6.3.0.22-ISS-ITDS

Alternatively, upgrade GSKit to 7.0.4.45 or 8.0.50.4 or later.
