ubuntu

February 28, 2023

Several security issues were fixed in OpenJDK.

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)
