The vulnerability of the Network Security Services library allows a perpetrator to trigger a service failure or exert other effects.

The vulnerability of the ssl3HandleECDHServerKeyExchange function in the Network Security Services library is related to the use of memory after it is freed. Exploiting this vulnerability could allow a malicious actor to cause service failures or other effects when establishing an SSL connection...

Apache Qpid Proton python API plaintext transfer vulnerability

Apache Qpid is an object-oriented messaging middleware developed by the Apache Software Foundation. The Proton python API is an API that supports the python language and implements the AMQP 1.0 protocol. A security vulnerability exists in the Apache Qpid Proton python API versions 0.9 through...

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 ...

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)

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 ...

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...

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...

The vulnerability of the ScreenOS operating system, which allows a hacker to trigger a service failure

The vulnerability of the L2TP packet processing function in the operating system ScreenOS exists due to insufficient checks on input data. Exploiting this vulnerability can allow a malicious actor, operating remotely, to cause service failures using specially created L2TP packets...

USN-2904-1 thunderbird vulnerabilities

Karthikeyan Bhargavan and Gaetan Leurent discovered that NSS incorrectly allowed MD5 to be used for TLS 1.2 connections. If a remote attacker were able to perform a machine-in-the-middle attack, this flaw could be exploited to view sensitive information. CVE-2015-7575 Yves Younan discovered that...

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...

DEBIAN-CVE-2016-0703

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 accepts a nonzero CLIENT-MASTER-KEY CLEAR-KEY-LENGTH value for an arbitrary cipher, which allows man-in-the-middle attackers to...

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...

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...
