NVD Description

Note: Versions mentioned in the description apply only to the upstream python-rsa package and not the python-rsa package as distributed by RHEL.

It was found that python-rsa is vulnerable to Bleichenbacher timing attacks. An attacker can use this flaw via the RSA decryption API to decrypt parts of the cipher text encrypted with RSA.
