QID 980890: Java (maven) Security Update for org.bouncycastle:bcprov-jdk15 (GHSA-r9ch-m4fh-fc7q)

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.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
