openjdk-8 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.10
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 ESM

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)
