DEBIAN-CVE-2016-0800
The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a ServerVerify message before establishing that a client possesses certain plaintext RSA data, which makes it easier for remote attackers to decrypt TLS ciphertext data by...
OpenSSL: SSLv2 doesn't block disabled ciphers
A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2 ciphers that were 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...
SUSE-SU-2016:0624-1 Security update for openssl
This update for openssl fixes various security issues and bugs: Security issues fixed: - CVE-2016-0800 aka the 'DROWN' attack bsc968046: OpenSSL was vulnerable to a cross-protocol attack that could lead to decryption of TLS sessions by using a server supporting SSLv2 and EXPORT cipher suites as a...

openssl: assertion failure in SSLv2 servers
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...
openssl: assertion failure in SSLv2 servers

openssl: Divide-and-conquer session key recovery in SSLv2
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...

DEBIAN-CVE-2015-3197
ssl/s2srvr.c in OpenSSL 1.0.1 before 1.0.1r and 1.0.2 before 1.0.2f does not prevent use of disabled ciphers, which makes it easier for man-in-the-middle attackers to defeat cryptographic protection mechanisms by performing computations on SSLv2 traffic, related to the getclientmasterkey and...

CVE-2015-0293
The SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service s2lib.c assertion failure and daemon exit via a crafted CLIENT-MASTER-KEY message...
USN-2537-1 openssl vulnerabilities
It was discovered that OpenSSL incorrectly handled malformed EC private key files. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service, or execute arbitrary code. CVE-2015-0209 Stephen Henson discovered that OpenSSL incorrectly handled...
