Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DSA-3299-1)
Summary:	The remote host is missing an update for the Debian 'stunnel4' package(s) announced via the DSA-3299-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'stunnel4' package(s) announced via the DSA-3299-1 advisory. Vulnerability Insight: 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. For the stable distribution (jessie), this problem has been fixed in version 3:5.06-2+deb8u1. For the testing distribution (stretch), this problem has been fixed in version 3:5.18-1. For the unstable distribution (sid), this problem has been fixed in version 3:5.18-1. We recommend that you upgrade your stunnel4 packages. Affected Software/OS: 'stunnel4' package(s) on Debian 8. Solution: Please install the updated package(s). CVSS Score: 5.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:N
