USN-6527-1: OpenJDK vulnerabilities

Ubuntu Security Advisory

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)
