These cryptographic - operations are vulnerable to oracle attacks, including via side channels such - as timing or cache-based analysis. In theory it would be possible to attack - the previous implementations using such a side channel, which could allow - an attacker to mount a plaintext recovery attack. +* CVE-2015-7824: An information leak allowed padding oracle attacks against + TLS CBC decryption. Found in a review by Sirrix AG and 3curity GmbH. + +* CVE-2015-7825: Validating a malformed certificate chain could cause an + infinite loop. Found in a review by Sirrix AG and 3curity GmbH. + +* CVE-2015-7826: X.509 path validation violated RFC 6125 and would accept + certificates which should not validate under those rules. In particular botan + would accept wildcard certificates as matching in situations where it should + not (for example it would erronously accept '*.example.com' as a valid + wildcard for 'foo.bar.example.com') + +* CVE-2015-7827: The routines for decoding PKCS #1 encryption and OAEP blocks + have been rewritten to run without secret indexes or branches.

In theory it would be + possible to attack the previous implementations using such a side channel, + which could allow an attacker to mount a plaintext recovery attack. By writing the code such that it does not depend on secret inputs for branch or memory indexes, such a side channel would be much less likely to exist. |
