"Steven Vittitoe reported multiple stack buffer overflows in Linux
kernel's magicmouse HID driver. A physically proximate attacker could
exploit this flaw to cause a denial of service (system crash) or
possibly execute arbitrary code via specially crafted devices.
(CVE-2014-3181)

Ben Hawkes reported some off by one errors for report descriptors in
the Linux kernel's HID stack. A physically proximate attacker could
exploit these flaws to cause a denial of service (out-of-bounds write)
via a specially crafted device. (CVE-2014-3184)

Several bounds check flaws allowing for buffer overflows were
discovered in the Linux kernel's Whiteheat USB serial driver. A
physically proximate attacker could exploit these flaws to cause a
denial of service (system crash) via a specially crafted device.
(CVE-2014-3185)

Steven Vittitoe reported a buffer overflow in the Linux kernel's
PicoLCD HID device driver. A physically proximate attacker could
exploit this flaw to cause a denial of service (system crash) or
possibly execute arbitrary code via a specially craft device.
(CVE-2014-3186)

A flaw was discovered in the Linux kernel's UDF filesystem (used on
some CD-ROMs and DVDs) when processing indirect ICBs. An attacker who
can cause CD, DVD or image file with a specially crafted inode to be
mounted can cause a denial of service (infinite loop or stack
consumption). (CVE-2014-6410)

James Eckersall discovered a buffer overflow in the Ceph filesystem in
the Linux kernel. A remote attacker could exploit this flaw to cause a
denial of service (memory consumption and panic) or possibly have
other unspecified impact via a long unencrypted auth ticket.
(CVE-2014-6416)

James Eckersall discovered a flaw in the handling of memory allocation
failures in the Ceph filesystem. A remote attacker could exploit this
flaw to cause a denial of service (system crash) or possibly have
unspecified other impact. (CVE-2014-6417)

James Eckersall discovered a flaw in how the Ceph filesystem validates
auth replies. A remote attacker could exploit this flaw to cause a
denial of service (system crash) or possibly have other unspecified
impact. (CVE-2014-6418).

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