Summary
openjdk-8 vulnerabilities
Details

It was discovered that the Serialization component of OpenJDK did not properly handle the deserialization of some CORBA objects. An attacker could possibly use this to bypass Java sandbox restrictions. (CVE-2023-21830)

Markus Loewe discovered that the Java Sound subsystem in OpenJDK did not properly validate the origin of a Soundbank. An attacker could use this to specially craft an untrusted Java application or applet that could load a Soundbank from an attacker controlled remote URL. (CVE-2023-21843)
