local user could cause a denial of service (memory corruption or
panic) or possibly have unspecified impact via the keyctl commands.
(CVE-2014-9529)

A memory leak was discovered in the ISO 9660 CDROM file system when
parsing rock ridge ER records. A local user could exploit this flaw to
obtain sensitive information from kernel memory via a crafted iso9660
image. (CVE-2014-9584).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
