IBM HTTP Server 8.0.x < 8.0.0.9 / 8.5.x < 8.5.5.3 (247195)

low Nessus Plugin ID 144766
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote web server is affected by a vulnerability.

Description

The version of IBM HTTP Server running on the remote host is affected by a vulnerability. The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to IBM HTTP Server version 8.5.5.3, 8.0.0.9, or later. Alternatively, upgrade to the minimal fix pack levels required by the interim fix and then apply Interim Fix PI19700.
