It was discovered that the HotSpot VM implementation in OpenJDK did not
properly validate bytecode blocks in certain situations. An attacker could
possibly use this to cause a denial of service. (CVE-2022-40433)
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 the CORBA implementation in OpenJDK did not properly
perform deserialization of IOR string objects. An attacker could possibly
use this to bypass Java sandbox restrictions. (CVE-2023-22067)
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)
