   SUSE Security Update: Security update for python-cryptography
______________________________________________________________________________

Announcement ID: SUSE-SU-2018:3392-1
Rating: moderate
References: #1101820
Cross-References: CVE-2018-10903
Affected Products:
SUSE Linux Enterprise Module for Basesystem 15
______________________________________________________________________________

An update that fixes one vulnerability is now available.

Description:

This update for python-cryptography fixes the following issues:

- CVE-2018-10903: 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 could have caused key
leakage (bsc#1101820).


Patch Instructions:

To install this SUSE Security Update use the SUSE recommended installation
methods
