Descriptions

Unspecified vulnerability in Oracle Java SE 6u121, 7u111, 8u102; and Java SE Embedded 8u101 allows remote attackers to affect integrity via vectors related to JMX.

Vulnerabilidad no especificada en Oracle Java SE 6u121, 7u111, 8u102 y Java SE Embedded 8u101 permite a atacantes remotos afectar a la integridad a través de vectores relacionados con JMX.

A flaw was found in the way the JMX component of OpenJDK handled classloaders. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.

It was discovered that the Hotspot component of OpenJDK did not properly check arguments of the System.arraycopy function in certain cases. An attacker could use this to bypass Java sandbox restrictions. It was discovered that OpenJDK did not restrict the set of algorithms used for Jar integrity verification. An attacker could use this to modify without detection the content of a JAR file, affecting system integrity. Various other issues were also addressed.
