| Package(s): | stunnel4 | CVE #(s): | CVE-2015-3644 | ||||||||
| Created: | July 3, 2015 | Updated: | July 28, 2015 | ||||||||
| Description: | From the Debian advisory: Johan Olofsson discovered an authentication bypass vulnerability in Stunnel, a program designed to work as an universal SSL tunnel for network daemons. When Stunnel in server mode is used with the redirect option and certificate-based authentication is enabled with "verify = 2" or higher, then only the initial connection is redirected to the hosts specified with "redirect". This allows a remote attacker to bypass authentication. | ||||||||||
