NVD Description
Note: Versions mentioned in the description apply only to the upstream python-twisted-web package and not the python-twisted-web package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
In the Bouncy Castle JCE Provider version 1.55 and earlier DSA signature generation is vulnerable to timing attack. Where timings can be closely observed for the generation of signatures, the lack of blinding in 1.55, or earlier, may allow an attacker to gain information about the signature's k value and ultimately the private value as well.
