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: 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...

SSL/TLS: Cross-protocol attack on TLS using SSLv2 (DROWN)

A padding oracle flaw was found in the Secure Sockets Layer version 2.0 SSLv2 protocol. An attacker could 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 ...

UBUNTU-CVE-2016-1978

Use-after-free vulnerability in the ssl3HandleECDHServerKeyExchange function in Mozilla Network Security Services NSS before 3.21, as used in Mozilla Firefox before 44.0, allows remote attackers to cause a denial of service or possibly have unspecified other impact by making an SSL 1 DHE or 2 ECD...

DEBIAN-CVE-2016-0704

An oracle protection mechanism in the getclientmasterkey function in s2srvr.c in 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 overwrites incorrect MASTER-KEY bytes during use of export cipher suites, which makes it easier fo...

OpenSSL SSLv2 Partitioned Session Key Recovery Vulnerability

OpenSSL is an open source implementation of SSL used to enable strong encryption of network communications and is now widely used in a variety of web applications. A security vulnerability in s2srvr.c in OpenSSL 1.0.2, 1.0.1l, 1.0.0q, 0.9.8ze and earlier versions that does not ensure that the...

Logstash 2.2.1 Elasticsearch Output Vulnerability

Logstash version 2.2.1 is vulnerable to a man in the middle attack when used with Elasticsearch output. In version 2.2.1, the config which enables SSL/TLS default has been disabled inadvertently, so a malicious user could access payload data sent via HTTP during the initial handshake. This has be...
