openSUSE Security Update : python-cryptography (openSUSE-2018-1281)

Medium Nessus Plugin ID 118451

Synopsis

The remote openSUSE host is missing a security update.

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).

This update was imported from the SUSE:SLE-15:Update update project.

Solution

Update the affected python-cryptography packages.
