script_tag(name:"insight", value:"OpenSSL is a toolkit that implements the
Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols,
as well as a full-strength, general purpose cryptography library.
A padding oracle flaw was found in the Secure Sockets Layer version 2.0
(SSLv2) protocol. An attacker can potentially use this flaw to decrypt
RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol
version, allowing them to decrypt such connections. This cross-protocol
attack is publicly referred to as DROWN. (CVE-2016-0800)
Note: This issue was addressed by disabling the SSLv2 protocol by default
when using the 'SSLv23' connection methods, and removing support for weak
SSLv2 cipher suites. For more information, refer to the knowledge base
article linked to in the References section.
It was discovered that the SSLv2 servers using OpenSSL accepted SSLv2
connection handshakes that indicated non-zero clear key length for
non-export cipher suites. An attacker could use this flaw to decrypt
recorded SSLv2 sessions with the server by using it as a decryption
oracle.(CVE-2016-0703)
It was discovered that the SSLv2 protocol implementation in OpenSSL did
not properly implement the Bleichenbacher protection for export cipher
suites. An attacker could use a SSLv2 server using OpenSSL as a
Bleichenbacher oracle. (CVE-2016-0704)
Note: The CVE-2016-0703 and CVE-2016-0704 issues could allow for more
efficient exploitation of the CVE-2016-0800 issue via the DROWN attack.
A denial of service flaw was found in the way OpenSSL handled SSLv2
handshake messages. A remote attacker could use this flaw to cause a
TLS/SSL server using OpenSSL to exit on a failed assertion if it had both
the SSLv2 protocol and EXPORT-grade cipher suites enabled. (CVE-2015-0293)
A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2
ciphers that have been disabled on the server. This could result in weak
SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to
man-in-the-middle attacks. (CVE-2015-3197)
Red Hat would like to thank the OpenSSL project for reporting these issues.
