Ubuntu Security Notice 2356-1 - Jack Morgenstein reported a flaw in the page handling of the KVM (Kerenl Virtual Machine) subsystem in the Linux kernel. A guest OS user could exploit this flaw to cause a denial of service (host OS memory corruption) or possibly have other unspecified impact on the host OS. Chris Evans reported an flaw in the Linux kernel's handling of iso9660 (compact disk filesystem) images. An attacker who can mount a custom iso9660 image either via a CD/DVD drive or a loopback mount could cause a denial of service (system crash or reboot). Various other issues were also addressed.

It was discovered that the implementation of org.hibernate.validator.util.ReflectionHelper together with the permissions required to run Hibernate Validator under the Java Security Manager could allow a malicious application deployed in the same application container to execute several actions with escalated privileges, which might otherwise not be possible. This flaw could be used to perform various attacks, including but not restricted to, arbitrary code execution in systems that are otherwise secured by the Java Security Manager.

If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to cause APT to crash, resulting in a denial of service, or possibly execute arbitrary code. In addition, this update fixes regressions introduced by the USN-2348-1 security update: APT incorrectly handled file:/// sources on a different partition, incorrectly handled Dir::state::lists set to a relative path, and incorrectly handled cdrom: sources. Various other issues were also addressed.
