Ubuntu Security Notice USN-3130-1

Ubuntu Security Notice 3130-1 – 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. It was discovered that the JMX component of OpenJDK did not sufficiently perform classloader consistency checks. An attacker could use this to bypass Java sandbox restrictions. Various other issues were also addressed.

Red Hat Security Advisory 2016-2802-01 – OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, as well as a full-strength general-purpose cryptography library. Security Fix: A memory leak flaw was found in the way OpenSSL handled TLS status request extension data during session renegotiation. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling support.
