It was discovered that crypto provider implementations in the JCE component of OpenJDK for crypto algorithms such as AES or SHA did not perform array bounds checks. This could lead to out-of-bounds access if compiler intrinsics were used instead of the Java runtime implementations of the specific operations.

It was discovered that the AccessController class implementation in the Security component of OpenJDK failed, in certain cases, to consider the current context and correctly restrict privileges based on it. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.

It was discovered that the Security component of OpenJDK did not correctly perform merging of multiple sections for the same file listed in the JAR archive file manifest. An attacker could possibly use this flaw to alter certain attributes specified in the manifest without changing archive signature.

A memory disclosure flaw was found in the FileChannelImpl class in the Libraries component of OpenJDK. An untrusted Java application or applet could use this flaw leak limited amount of Java Virtual Machine memory possibly containing sensitive information, resulting in a partial bypass of Java sandbox restrictions.

An information leak flaw was found in the Networking component of OpenJDK. The HttpURLConnection class implementation could re-send HTTP headers containing sensitive data (such as Cookie or Authorization headers) to a different host when following HTTP redirects. This could lead to exposure of data to unintended HTTP hosts.

It was discovered that the Security component of OpenJDK could incorrectly use unsigned manifest attribute entries when only properly signed entries were meant to be used. This could lead to bypass of protections provided by Jar signing. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
