FKIE_CVE-2015-7940
Vulnerability from fkie_nvd - Published: 2015-11-09 16:59 - Updated: 2026-06-17 00:33
Severity
Summary
The Bouncy Castle Java library before 1.51 does not validate a point is withing the elliptic curve, which makes it easier for remote attackers to obtain private keys via a series of crafted elliptic curve Diffie Hellman (ECDH) key exchanges, aka an "invalid curve attack."
