openssl: DoS when sending invalid DTLS handshake
A denial of service flaw was found in the way OpenSSL handled certain DTLS ServerHello requests. A specially crafted DTLS handshake packet could cause a DTLS client using OpenSSL to crash...
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...

UBUNTU-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...

UBUNTU-CVE-2014-0221
The dtls1getmessagefragment function in d1both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service recursion and client crash via a DTLS hello message in an invalid DTLS handshake...

openssl: client-side denial of service when using anonymous ECDH
The ssl3sendclientkeyexchange function in s3clnt.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h, when an anonymous ECDH cipher suite is used, allows remote attackers to cause a denial of service NULL pointer dereference and client crash by triggering a NULL certificate...
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...
OpenSSL -- multiple vulnerabilities
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...
OpenSSL 'ChangeCipherSpec' MiTM Potential Vulnerability
The OpenSSL service on the remote host is potentially vulnerable to a man-in-the-middle MiTM attack, based on its response to two consecutive 'ChangeCipherSpec' messages during the incorrect phase of an SSL/TLS handshake. This flaw could allow a MiTM attacker to decrypt or forge SSL messages by...
gnutls: insufficient session id length check in _gnutls_read_server_hello (GNUTLS-SA-2014-3)
A flaw was found in the way GnuTLS parsed session IDs from ServerHello messages of the TLS/SSL handshake. A malicious server could use this flaw to send an excessively long session ID value, which would trigger a buffer overflow in a connecting TLS/SSL client application using GnuTLS, causing the...

Scientific Linux Security Update : curl on SL6.x i386/x86_64 (20140527)
It was found that libcurl could incorrectly reuse existing connections for requests that should have used different or no authentication credentials, when using one of the following protocols: HTTPS with NTLM authentication, LDAPS, SCP, or SFTP. If an application using the libcurl library connect...
Ubuntu 12.04 LTS : linux-lts-quantal vulnerabilities (USN-2223-1)
