CVE-2014-3511

Publication date 7 August 2014

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 1.0.1 before 1.0.1i allows man-in-the-middle attackers to force the use of TLS 1.0 by triggering ClientHello message fragmentation in communication between a client and server that both support later TLS versions, related to a "protocol downgrade" issue.
