-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-3299-1 security@xxxxxxxxxx https://www.debian.org/security/ Salvatore Bonaccorso July 02, 2015 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : stunnel4 CVE ID : CVE-2015-3644 Debian Bug : 785352 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.
