Scientific Linux Security Update : java-1.8.0-openjdk on SL6.x i386/x86_64
Critical Nessus Plugin ID 90617
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionSecurity Fix(es) :
- Multiple flaws were discovered in the Serialization and Hotspot components in OpenJDK. An untrusted Java application or applet could use these flaws to completely bypass Java sandbox restrictions.
- It was discovered that the RMI server implementation in the JMX component in OpenJDK did not restrict which classes can be deserialized when deserializing authentication credentials. A remote, unauthenticated attacker able to connect to a JMX port could possibly use this flaw to trigger deserialization flaws.
- It was discovered that the JAXP component in OpenJDK failed to properly handle Unicode surrogate pairs used as part of the XML attribute values. Specially crafted XML input could cause a Java application to use an excessive amount of memory when parsed. (CVE-2016-3425)
- It was discovered that the GCM (Galois/Counter Mode) implementation in the JCE component in OpenJDK used a non-constant time comparison when comparing GCM authentication tags. A remote attacker could possibly use this flaw to determine the value of the authentication tag. (CVE-2016-3426)
- It was discovered that the Security component in OpenJDK failed to check the digest algorithm strength when generating DSA signatures. The use of a digest weaker than the key strength could lead to the generation of signatures that were weaker than expected.
SolutionUpdate the affected packages.
