Several security issues were fixed in OpenJDK 10.
It was discovered that OpenJDK did not properly validate types in some situations. An attacker could use this to construct a Java class that could possibly bypass sandbox restrictions. (CVE-2018-2825, CVE-2018-2826)

Several security issues were fixed in OpenJDK 10.
It was discovered that OpenJDK did not properly validate types in some situations. An attacker could use this to construct a Java class that could possibly bypass sandbox restrictions. (CVE-2018-2825, CVE-2018-2826)
It was discovered that the PatternSyntaxException class in OpenJDK did not properly validate arguments passed to it. An attacker could use this to potentially construct a class that caused a denial of service (excessive memory consumption). (CVE-2018-2952)
