| Title: | DSA-2664-1 stunnel4 - buffer overflow | ||
| Description: | Stunnel, a program designed to work as an universal SSL tunnel for network daemons, is prone to a buffer overflow vulnerability when using the Microsoft NT LAN Manager (NTLM) authentication (<q>protocolAuthentication = NTLM</q>) together with the <q>connect</q> protocol method (<q>protocol = connect</q>). With these prerequisites and using stunnel4 in SSL client mode (<q>client = yes</q>) on a 64 bit host, an attacker could possibly execute arbitrary code with the privileges of the stunnel process, if the attacker can either control the specified proxy server or perform man-in-the-middle attacks on the tcp session between stunnel and the proxy sever. | ||
