openssl: POLY1305 MAC implementation corrupts vector registers on PowerPC

A flaw was found in in the POLY1305 MAC message authentication code implementation in OpenSSL, affecting applications running on PowerPC CPU-based platforms that utilize vector instructions, and has the potential to corrupt the internal state of these applications. If an attacker can manipulate t...

The POLY1305 MAC (message authentication code) implementation contains a bug that might corrupt the internal state of applications running on PowerPC CPU based platforms

OpenSSL contains an issue in the POLY1305 MAC message authentication code implementation that might result in a corrupted internal application state. This flaw is only exploitable on PowerPC CPU based platforms if the CPU provides vector instructions PowerISA 2.07. The impact of the corrupted...

ssh: Prefix truncation attack on Binary Packet Protocol (BPP)

A flaw was found in the SSH channel integrity. By manipulating sequence numbers during the handshake, an attacker can remove the initial messages on the secure channel without causing a MAC failure. For example, an attacker could disable the ping extension and thus disable the new countermeasure ...
