medium Nessus Plugin ID 65863

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

An updated stunnel package that fixes one security issue is now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

stunnel is a socket wrapper which can provide SSL (Secure Sockets Layer) support to ordinary applications. For example, it can be used in conjunction with imapd to create an SSL-secure IMAP server.

An integer conversion issue was found in stunnel when using Microsoft NT LAN Manager (NTLM) authentication with the HTTP CONNECT tunneling method. With this configuration, and using stunnel in SSL client mode on a 64-bit system, an attacker could possibly execute arbitrary code with the privileges of the stunnel process via a man-in-the-middle attack or by tricking a user into using a malicious proxy.
(CVE-2013-1762)

All stunnel users should upgrade to this updated package, which contains a backported patch to correct this issue.

Solution

Update the affected stunnel and / or stunnel-debuginfo packages.
