USN-1998-1: Linux kernel vulnerabilities

First published: Tue Oct 22 2013(Updated: )

An information leak was discovered in the Linux kernel when reading broadcast messages from the notify_policy interface of the IPSec key_socket. A local user could exploit this flaw to examine potentially sensitive information in kernel memory. (CVE-2013-2237) 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 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 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 an information leak in the Linux kernel's Human Interface Device (HID) subsystem when CONFIG_HID_SENSOR_HUB is enabled. A physically proximate attacker could obtain potentially sensitive information from kernel memory via a specially crafted device. (CVE-2013-2898) Kees Cook discovered a flaw in the Human Interface Device (HID) subsystem of the Linux kernel whe CONFIG_HID_PICOLCD is enabled. A physically proximate attacker could exploit this flaw to cause a denial of service (OOPS) via a specially crafted device. (CVE-2013-2899) A flaw was discovered in how the Linux Kernel's networking stack checks scm credentials when used with namespaces. A local attacker could exploit this flaw to gain privileges. (CVE-2013-4300)
