CVE-2016-6298  (opens in a new tab)
CWE-200  (opens in a new tab)

How to fix?

Upgrade Debian:11 python-jwcrypto to version 0.3.2-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-jwcrypto package and not the python-jwcrypto package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

The _Rsa15 class in the RSA 1.5 algorithm implementation in jwa.py in jwcrypto before 0.3.2 lacks the Random Filling protection mechanism, which makes it easier for remote attackers to obtain cleartext data via a Million Message Attack (MMA).
