QID 980891

QID 980891: Java (maven) Security Update for org.bouncycastle:bcprov-jdk15 (GHSA-r97x-3g8f-gx3m)

In the Bouncy Castle JCE Provider versions 1.51 to 1.55, a carry propagation bug was introduced in the implementation of squaring for several raw math classes have been fixed (org.bouncycastle.math.raw.Nat???). These classes are used by our custom elliptic curve implementations (org.bouncycastle.math.ec.custom.**), so there was the possibility of rare (in general usage) spurious calculations for elliptic curve scalar multiplications. Such errors would have been detected with high probability by the output validation for our scalar multipliers.

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

CVSS V3 rated as High - 7.5 severity.

CVSS V2 rated as Medium - 5 severity.
