CVE-2014-3569: OpenSSL

Medium severity, CVSS 5.0. EPSS: 19.5% chance of exploitation in the next 30 days.

The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 0.9.8zc, 1.0.0o, and 1.0.1j does not properly handle attempts to use unsupported protocols, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an unexpected handshake, as demonstrated by an SSLv3 handshake to a no-ssl3 application with certain error handling. NOTE: this issue became relevant after the CVE-2014-3568 fix.

Affected products

• OpenSSL OpenSSL: version 1.0.1j only
