Descriptions

Unspecified vulnerability in Oracle Java SE 6u95, 7u80, and 8u45; JRockit R28.3.6; and Java SE Embedded 7u75 and 8u33 allows remote attackers to affect availability via vectors related to JNDI.

Vulnerabilidad no especificada en Oracle Java SE 6u95, 7u80 y 8u45; JRockit R28.3.6; y Java SE Embedded 7u75 y 8u33, permite a atacantes remotos afectar la disponibilidad a través de vectores relacionados con JNDI.

It was discovered that the JNDI component in OpenJDK did not handle DNS resolution errors correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution.

The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Java Software Development Kit. Multiple flaws were discovered in the 2D, CORBA, JMX, Libraries and RMI components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. A flaw was found in the way the Libraries component of OpenJDK verified Online Certificate Status Protocol responses. An OCSP response with no nextUpdate date specified was incorrectly handled as having unlimited validity, possibly causing a revoked X.509 certificate to be interpreted as valid.
