Critical

A boundary check flaw was found in the font parsing code in the 2D component in OpenJDK. A specially crafted font file could allow an untrusted Java application or applet to disclose portions of the Java Virtual Machine memory.

CWE-125 - Out-of-bounds Read

A NULL pointer dereference flaw was found in the MulticastSocket implementation in the Libraries component of OpenJDK. An untrusted Java application or applet could possibly use this flaw to bypass certain Java sandbox restrictions.

CWE-476 - NULL Pointer Dereference

A boundary check flaw was found in the font parsing code in the 2D component in OpenJDK. A specially crafted font file could allow an untrusted Java application or applet to disclose portions of the Java Virtual Machine memory.

CWE-125 - Out-of-bounds Read

It was discovered that the SSL/TLS implementation in the JSSE component in OpenJDK failed to properly check whether the ChangeCipherSpec was received during the SSL/TLS connection handshake. An MITM attacker could possibly use this flaw to force a connection to be established without encryption being enabled.

Unspecified vulnerability in the Java Virtual Machine (JVM) in IBM SDK, Java Technology Edition 5.0 before SR16-FP9, 6 before SR16-FP3, 6R1 before SR8-FP3, 7 before SR8-FP10, and 7R1 before SR2-FP10 allows remote attackers to escape the Java sandbox and execute arbitrary code via unspecified vectors related to the security manager.
