Formally Modeling the Terrapin Attack on SSH

The Terrapin attack against SSH channel integrity USENIX Security 2024 used a novel attack vector: attacks on the channel state. Surprisingly, not all AEAD modes of SSH were equally affected by this attack, and it remained an open question if "unaffected" meant "secure". Existing formal models fo...

Astra Linux – Vulnerability in PHP 7.3

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23, and 7.4.x below 7.4.11, when AES-CCM mode is used with the opensslencrypt function and a 12-byte IV is provided, only the first 7 bytes of the IV are actually used. This can result in reduced security and incorrect encrypted data...
