SUSE update for python-cryptography, python-cryptography-vectors

1) Information disclosure

EUVDB-ID: #VU15945

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-10903

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

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.
