Several vulnerabilities have been discovered in the OpenJDK Java runtime, which could result in denial of service, information disclosure, bypass of access/sandbox restrictions or the acceptance of untrusted certificates.
For the stable distribution (buster), these problems have been fixed in version 11.0.9+11-1~deb10u1.
We recommend that you upgrade your openjdk-11 packages.
