USN-5897-1: OpenJDK vulnerabilities


=========================================================================
Ubuntu Security Notice USN-5897-1
February 28, 2023

openjdk-17, openjdk-19, openjdk-lts 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

Summary:

Several security issues were fixed in OpenJDK.

Software Description:
- openjdk-17: Open Source Java implementation
- openjdk-19: Open Source Java implementation
- openjdk-lts: Open Source Java implementation

Details:

Juraj Somorovsky, Marcel Maehren, Nurullah Erinola, and Robert Merget
discovered that the DTLS implementation in the JSSE subsystem of OpenJDK
did not properly restrict handshake initiation requests from clients. A
remote attacker could possibly use this to cause a denial of service.
(CVE-2023-21835)

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)
