DEBIAN-CVE-2010-3075

EncFS before 1.7.0 encrypts multiple blocks by means of the CFB cipher mode with the same initialization vector, which makes it easier for local users to obtain sensitive information via calculations involving recovery of XORed data, as demonstrated by an attack on encrypted data in which the las...

CVE-2005-0366

The integrity check feature in OpenPGP, when handling a message that was encrypted using cipher feedback CFB mode, allows remote attackers to recover part of the plaintext via a chosen-ciphertext attack when the first 2 bytes of a message block are known, and an oracle or other mechanism is...

OpenPGP vulnerable to chosen-ciphertext attacks in cipher feedback (CFB) mode

Overview A vulnerability in OpenPGP may allow attackers to recover partial plaintexts from OpenPGP messages that use symmetric encryption. Description A vulnerability in OpenPGP can be used by attackers to recover partial plaintexts from messages employing symmetric encryption. Researchers Serge...

CVE-1999-1085

SSH 1.2.25, 1.2.23, and other versions, when used in in CBC Cipher Block Chaining or CFB Cipher Feedback 64 bits modes, allows remote attackers to insert arbitrary data into an existing stream between an SSH client and server by using a known plaintext attack and computing a valid CRC-32 checksum...

Weak CRC allows packet injection into SSH sessions encrypted with block ciphers

Overview There is an information integrity vulnerability in the SSH1 protocol that allows packets encrypted with a block cipher to be modified without notice. Description Preconditions: Attacker has a fragment of plaintext and its corresponding ciphertext. Attacker must be able to actively...
