Mandriva Linux Security Advisory : stunnel (MDVSA-2013:130)

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing a security update.

Description :

Updated stunnel packages fix security vulnerability :

stunnel 4.21 through 4.54, when CONNECT protocol negotiation and NTLM
authentication are enabled, does not correctly perform integer
conversion, which allows remote proxy servers to execute arbitrary
code via a crafted request that triggers a buffer overflow
(CVE-2013-1762).

The updated packages also fixes the following :

- move library subpackages back into main stunnel package

- add a systemd unit file (partially fixing Bug 3951)

- fix issues with stunnel.conf and stunnel.pem, with
stunnel running in a chroot environment.
