FreeBSD : OpenSSL -- multiple vulnerabilities (5ac53801-ec2e-11e3-9cf3-3c970e169bc2)
The OpenSSL Project reports : An attacker using a carefully crafted handshake can force the use of weak keying material in OpenSSL SSL/TLS clients and servers. This can be exploited by a Man-in-the-middle MITM attack where the attacker can decrypt and modify traffic from the attacked client and...
JVN#61247051: OpenSSL improper handling of Change Cipher Spec message
OpenSSL contains a flaw in the implementation of the Change Cipher Spec protocol that allows a MITM man-in-the-middle attacker to force a server and a client to use easily guessable cryptgraphic key material during the initial SSL/TLS handshake CWE-325. Impact SSL/TLS communication between the...
DEBIAN-CVE-2014-0224
OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessio...

CVE-2014-0224
CVE-2014-0224 describes an OpenSSL ChangeCipherSpec (CCS) handling flaw that can enable a Man-in-the-Middle to force use of weak key material in TLS/SSL sessions, allowing traffic decryption or modification between vulnerable client and server. The initial OpenSSL disclosures specify affected ser...

openssl: SSL/TLS MITM vulnerability
It was found that OpenSSL clients and servers could be forced, via a specially crafted handshake packet, to use weak keying material for communication. A man-in-the-middle attacker could use this flaw to decrypt and modify traffic between a client and a server...
