USN-6527-1: OpenJDK vulnerabilities

Releases

• Ubuntu 23.10
• Ubuntu 23.04
• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS
• Ubuntu 18.04 ESM

Packages

• openjdk-17 - Open Source Java implementation
• openjdk-21 - Open Source Java implementation
• openjdk-lts - Open Source Java implementation

Details

Carter Kozak discovered that OpenJDK, when compiling with AVX-512
instruction support enabled, could produce code that resulted in memory
corruption in certain situations. An attacker targeting applications built
in this way could possibly use this to cause a denial of service or execute
arbitrary code. In Ubuntu, OpenJDK defaults to not using AVX-512
instructions. (CVE-2023-22025)

It was discovered that OpenJDK did not properly perform PKIX certification
path validation in certain situations. An attacker could use this to cause
a denial of service. (CVE-2023-22081)
