1) Information disclosure

EUVDB-ID: #VU15945

Risk: Low

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information.

The vulnerability exists due to due to insufficient enforcement of a minimum tag length prior to passing user-supplied input to the finalize_with_tag API. A remote attacker can send a specially crafted request that submits a malicious short tag length, trigger key leakage and access sensitive information.

Mitigation

Update the affected package python-cryptography, python-cryptography-vectors to the latest version.
