REDHAT-BUG-2075821
First published: Fri Apr 15 2022(Updated: )
It was discovered that the Libraries component in OpenJDK failed to properly verify ECDSA (Elliptic Curve Digital Signature Algorithm) signatures. A remote attacker could use this flaw to make a Java application compute an invalid signature for arbitrary forged content, thus bypassing the signature verification process.
