An information leak was discovered in the handling of ICMPv6 Router Advertisement (RA) messages in the Linux kernel's IPv6 network stack. A remote attacker could exploit this flaw to cause a denial of service (excessive retries and address-generation outage), and consequently obtain sensitive information. (CVE-2013-0343) A flaw was discovered in the Xen subsystem of the Linux kernel when it provides read-only access to a disk that supports TRIM or SCSI UNMAP to a guest OS. A privileged user in the guest OS could exploit this flaw to destroy data on the disk, even though the guest OS should not be able to write to the disk. (CVE-2013-2140) Kees Cook discovered flaw in the Human Interface Device (HID) subsystem of the Linux kernel. A physically proximate attacker could exploit this flaw to execute arbitrary code or cause a denial of service (heap memory corruption) via a specially crafted device that provides an invalid Report ID. (CVE-2013-2888) Kees Cook discovered flaw in the Human Interface Device (HID) subsystem when CONFIG_HID_ZEROPLUS is enabled. A physically proximate attacker could leverage this flaw to cause a denial of service via a specially crafted device. (CVE-2013-2889) Kees Cook discovered a flaw in the Human Interface Device (HID) subsystem of the Linux kerenl when CONFIG_HID_PANTHERLORD is enabled. A physically proximate attacker could cause a denial of service (heap out-of-bounds write) via a specially crafted device. (CVE-2013-2892) Kees Cook discovered another flaw in the Human Interface Device (HID) subsystem of the Linux kernel when any of CONFIG_LOGITECH_FF, CONFIG_LOGIG940_FF, or CONFIG_LOGIWHEELS_FF are enabled. A physcially proximate attacker can leverage this flaw to cause a denial of service vias a specially crafted device. (CVE-2013-2893) Kees Cook discovered another flaw in the Human Interface Device (HID) subsystem of the Linux kernel when CONFIG_HID_LOGITECH_DJ is enabled. A physically proximate attacker could cause a denial of service (OOPS) or obtain sensitive information from kernel memory via a specially crafted device. (CVE-2013-2895) Kees Cook discovered a vulnerability in the Linux Kernel's Human Interface Device (HID) subsystem's support for N-Trig touch screens. A physically proximate attacker could exploit this flaw to cause a denial of service (OOPS) via a specially crafted device. (CVE-2013-2896) Kees Cook discovered yet another flaw in the Human Interface Device (HID) subsystem of the Linux kernel when CONFIG_HID_MULTITOUCH is enabled. A physically proximate attacker could leverage this flaw to cause a denial of service (OOPS) via a specia ... Description truncated, for more information please check the Reference URL
