Some API callers may use the returned (incorrect and attacker controlled) length field in a way which later caused memory corruption or other failure (bsc#1013209).\n- CVE-2016-2194: The ressol function in Botan allowed remote attackers to cause a denial of service (infinite loop) via unspecified input to the OS2ECP function, related to a composite modulus (bsc#965621).\n- CVE-2016-2195: Integer overflow in the PointGFp constructor in Botan allowed remote attackers to overwrite memory and possibly execute arbitrary code via a crafted ECC point, which triggers a heap-based buffer overflow (bsc#965620).\n- CVE-2017-2801: Incorrect comparison in X.509 DN strings (bsc#1033605).\n- CVE-2014-9742: The Miller-Rabin primality check in Botan improperly used a single random base, which made it easier for remote attackers to defeat cryptographic protection mechanisms via a DH group (bsc#974521).\n\nThese non-security issues were fixed:\n\n- Fixed EAX tag verification to run in constant time\n- The default TLS policy now disables SSLv3.\n- A crash could have occured when reading from a blocking random device if the\n  device initially indicated that entropy was available but a concurrent\n  process drained the entropy pool before the read was initiated.\n- Fixed decoding indefinite length BER constructs that contain a context sensitive\n  tag of zero.\n- The key length limit on HMAC has been raised to 512 bytes, allowing the use\n  of very long passphrases with PBKDF2.\n- OAEP had two bugs, one of which allowed it to be used even if the key was\n  too small, and the other of which would cause a crash during decryption if\n  the EME data was too large for the associated key.\n","status":"published","published":"2017-05-09T11:34:34Z","modified":"2026-02-04T03:47:44.080543Z","updated_at":"2026-11-02T15:53:43.83457Z"}]}}
