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...

libkcapi: IV reuse in libkcapi one-shot symmetric cipher chunking causes cipher state reset across chunk boundaries

A flaw was found in libkcapi. When performing one-shot symmetric cipher operations on large inputs over 64 KiB in stateful modes such as Counter CTR or Cipher Block Chaining CBC, the library improperly reuses the Initialization Vector IV for each internal data chunk. A remote attacker could...

kernel: crypto: ccp - copy IV using skcipher ivsize

A flaw was found in the Linux kernel's cryptographic coprocessor CCP driver. When processing AFALG rfc3686-ctr-aes-ccp requests, the ccpaescomplete function attempts to restore more data than the allocated buffer for the Initialization Vector IV can hold. This leads to a buffer overrun, which can...
