February 28, 2023

Several security issues were fixed in OpenJDK.

Summary

Several security issues were fixed in OpenJDK.

Software Description:

- openjdk-8: Open Source Java implementation

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)
