stunnel < 5.01 OpenSSL Heartbeat Information Disclosure (Heartbleed)

high Nessus Plugin ID 73500

Language:

Synopsis

The remote Windows host contains a program that is affected by an information disclosure vulnerability.

Description

The version of stunnel installed on the remote host is prior to version 5.01. It is, therefore, affected by an information disclosure vulnerability in the bundled OpenSSL DLLs. A remote attacker can read the contents of up to 64KB of server memory, potentially exposing passwords, private keys, and other sensitive data.

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 stunnel version 5.01 or later.
