OpenSSL < 0.9.8m Multiple Vulnerabilities

medium Nessus Network Monitor Plugin ID 5358
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 host is vulnerable to multiple attack vectors.

Description

According to its banner, the remote host is running a version of OpenSSL older than 0.9.8m. Such versions potentially have the following vulnerabilities :

- Session renegotiations are not handled properly, which could be exploited to insert arbitrary plaintext by a man-in-the-middle. (CVE-2009-3555)

- The library does not check for a NULL return value from calls to the bn_wexpand() function, which has unspecified impact. (CVE-2009-3245)

Solution

Upgrade to OpenSSL 0.9.8m or later.
