The OpenSSL product processes X.509 certificates.

However, the X509_to_X509_REQ() function does not check if a pointer is NULL, before using it.

An attacker can therefore force a NULL pointer to be dereferenced in X509_to_X509_REQ() of OpenSSL, in order to trigger a denial of service.

Description of the vulnerability

The TLS protocol uses a series of messages which have to be exchanged between the client and the server, before establishing a secured session.

Several cryptographic algorithms can be negotiated, such as algorithms allowed for USA export (less than 512 bits).

An attacker, located as a Man-in-the-Middle, can inject during the session initialization a message choosing an export algorithm. This message should generate an error, however some TLS clients accept it.

Note: the variant related to Windows is described in VIGILANCE-VUL-16332.

An attacker, located as a Man-in-the-Middle, can therefore force the Chrome, JSSE, LibReSSL, Mono or OpenSSL client to accept a weak export algorithm, in order to more easily capture or alter exchanged data.

Description of the vulnerability

The TLS protocol uses a series of messages which have to be exchanged between the client and the server, before establishing a secured session.

However, clients such as JSSE or CyaSSL accept if the server directly skips to the final state (CVE-2014-6593, first analyzed in VIGILANCE-VUL-16014). Moreover, servers such as Mono or OpenSSL accept if the client directly skips to the final state (CVE-2015-0205, first analyzed in VIGILANCE-VUL-15934).The established session thus uses no encryption.

An attacker, who has a TLS server, can therefore force the JSSE, CyaSSL, Mono or OpenSSL client/server to use a clear text session, in order to allow a third party to capture or alter exchanged data.
