OpenSSH 6.2 and 6.3 AES-GCM Cipher Memory Corruption

According to its banner, the version of OpenSSH running on the remote host is version 6.2 or 6.3. It is, therefore, affected by a memory corruption vulnerability in post-authentication when the AES-GCM cipher is used for the key exchange. Exploitation of this vulnerability could lead to arbitrary...

Microsoft Warns Customers Away From RC4, SHA-1

The RC4 and SHA-1 algorithms have taken a lot of hits in recent years, with new attacks popping up on a regular basis. Many security experts and cryptographers have been recommending that vendors begin phasing the two out, and Microsoft on Tuesday said that is now recommending to developers that...

Security Advisory 2868725: Recommendation to disable RC4

In light of recent research into practical attacks on biases in the RC4 stream cipher, Microsoft is recommending that customers enable TLS1.2 in their services and take steps to retire and deprecate RC4 as used in their TLS implementations. Microsoft recommends TLS1.2 with AES-GCM as a more secur...
