DESCRIPTION

* CVE-2014-5077: Remote denial-of-service in SCTP on simultaneous connections.

Linux kernel built with the support for Stream Control Transmission
Protocol is vulnerable to a NULL pointer dereference flaw. It could occur
when simultaneous new connections are initiated between the same pair of
hosts. A remote user/program could use this flaw to crash the system kernel
resulting in denial-of-service.


* CVE-2014-3917: Denial-of-service and information leak in audit syscall subsystem.

Linux kernel built with the system-call auditing support is vulnerable to a
kernel crash or information disclosure flaw caused by out of bounds memory
access.  When system call audit rules are present on a system, an
unprivileged user could use this flaw to leak kernel memory or cause a
denial-of-service.
