Description:Summary:
The remote host is missing an update for the 'stunnel'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.

Affected Software/OS:
stunnel on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
