CVE-2014-3631

Status Candidate

Overview

The assoc_array_gc function in the associative-array implementation in lib/assoc_array.c in the Linux kernel before 3.16.3 does not properly implement garbage collection, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via multiple "keyctl newring" operations followed by a "keyctl timeout" operation.

Red Hat Security Advisory 2014-1971-01
Posted Dec 9, 2014

Red Hat Security Advisory 2014-1971-01 - A flaw was found in the way the Linux kernel's SCTP implementation handled malformed or duplicate Address Configuration Change Chunks. A remote attacker could use either of these flaws to crash the system. A flaw was found in the way the Linux kernel's SCTP implementation handled the association's output queue. A remote attacker could send specially crafted packets that would cause the system to use an excessive amount of memory, leading to a denial of service.

Ubuntu Security Notice USN-2379-1

Ubuntu Security Notice 2379-1 - 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. 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. Various other issues were also addressed.
