USN-1976-1: Linux kernel vulnerabilities

First published: Mon Sep 30 2013(Updated: )

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) 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)
