a/cryptsetup-2.4.3-x86_64-1.txz: Upgraded.
This update addresses a multi-step attack on LUKS2 format by orchestrating
LUKS2 reencryption metadata in existing LUKS2 header. An attacker is able to
trigger permanent data decryption (ciphertext->plaintext transformation) on
part of data device on next LUKS2 device activation. Attacker does _not_
have to know passphrase or decrypted volume encryption key.
cryptsetup versions older than 2.2.0 are not affected by this, because they
do not support online LUKS2 reencryption.
