______________________________________________________________________________
Announcement ID: SUSE-SU-2018:3553-1
Rating: moderate
References: #1101820
Cross-References: CVE-2018-10903
Affected Products:

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)
