Summary
This could have been exploited by passing python-jwcrypto a malicious
JWE token with a high compression ratio. When the server processed
said token, it would have consumed a lot of memory and processing
time.
For Debian 11 bullseye, this problem has been fixed in version
0.8.0-1+deb11u1.
We recommend that you upgrade your python-jwcrypto packages.
