CVE-2016-6298 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:20.10.
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 Ubuntu.
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).
