CVE-2018-10903 | 3 Canonical, Cryptography, Redhat | 3 Ubuntu Linux, Python-cryptography, Openstack | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
A flaw was found in python-cryptography versions between >=1.9.0 and <2.3. The finalize_with_tag API did not enforce a minimum tag length. If a user did not validate the input length prior to passing it to finalize_with_tag an attacker could craft an invalid payload with a shortened tag (e.g. 1 byte) such that they would have a 1 in 256 chance of passing the MAC check. GCM tag forgeries can cause key leakage. |
