Title:	Oracle OpenJDK ECDSA Signatures Vulnerability (CVE-2022-21449)
Summary:	Oracle OpenJDK is prone to vulnerability in the implementation; of ECDSA signature verification (Component: security-libs/java.security).
Description:	Summary: Oracle OpenJDK is prone to vulnerability in the implementation of ECDSA signature verification (Component: security-libs/java.security). Vulnerability Insight: The implementation of ECDSA signature verification didn't check if the two values r or s within an ECDSA signature were zero, so you could produce a signature value in which they are both 0 (appropriately encoded) and Java would accept it as a valid signature for any message and for any public key. Please seee the referenced 'Psychic Signatures in Java' blog post for more technical background info. Affected Software/OS: Oracle OpenJDK versions 15, 17 and 18. Solution: The vendor has released updates. Please see the references for more information. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:P/A:N
