Ubuntu: (Multiple Advisories) (CVE-2022-40433): OpenJDK 8 vulnerabilities
Description
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)
