"A flaw was discovered in the Linux kernel's compat ioctls for Adaptec
AACRAID scsi raid devices. An unprivileged local user could send
administrative commands to these devices potentially compromising the
data stored on the device. (CVE-2013-6383)

mpd reported an information leak in the recvfrom, recvmmsg, and
recvmsg system calls in the Linux kernel. An unprivileged local user
could exploit this flaw to obtain sensitive information from kernel
stack memory. (CVE-2013-7263)

mpb reported an information leak in the Layer Two Tunneling Protocol
(l2tp) of the Linux kernel. A local user could exploit this flaw to
obtain sensitive information from kernel stack memory. (CVE-2013-7264)

mpb reported an information leak in the Phone Network protocol
(phonet) in the Linux kernel. A local user could exploit this flaw to
obtain sensitive information from kernel stack memory. (CVE-2013-7265)

mpb reported an information leak in the Low-Rate Wireless Personal
Area Networks support (IEEE 802.15.4) in the Linux kernel. A local
user could exploit this flaw to obtain sensitive information from
kernel stack memory. (CVE-2013-7281).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
