CVE-2014-1438

Status Candidate

Overview

The restore_fpu_checking function in arch/x86/include/asm/fpu-internal.h in the Linux kernel before 3.12.8 on the AMD K7 and K8 platforms does not clear pending exceptions before proceeding to an EMMS instruction, which allows local users to cause a denial of service (task kill) or possibly gain privileges via a crafted application.

Ubuntu Security Notice 2234-1 - Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or gain administrative privileges. Dmitry Vyukov reported a flaw in the Linux kernel's handling of IPv6 UDP Fragmentation Offload (UFO) processing. A remote attacker could leverage this flaw to cause a denial of service (system crash). Hannes Frederic Sowa discovered a flaw in the Linux kernel's UDP Fragmentation Offload (UFO). An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or possibly gain administrative privileges. Various other issues were also addressed.

Red Hat Security Advisory 2014-0439-01
Posted Apr 28, 2014
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-0439-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A denial of service flaw was found in the way the Linux kernel's IPv6 implementation processed IPv6 router advertisement packets. An attacker able to send a large number of RA packets to a target system could potentially use this flaw to crash the target system. A flaw was found in the way the Linux kernel's netfilter connection tracking implementation for Datagram Congestion Control Protocol packets used the skb_header_pointer() function. A remote attacker could use this flaw to send a specially crafted DCCP packet to crash the system or, potentially, escalate their privileges on the system.

Mandriva Linux Security Advisory 2014-038
Posted Feb 18, 2014
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2014-038 - Multiple vulnerabilities has been found and corrected in the Linux kernel. The compat_sys_recvmmsg function in net/compat.c in the Linux kernel before 3.13.2, when CONFIG_X86_X32 is enabled, allows local users to gain privileges via a recvmmsg system call with a crafted timeout pointer parameter. The restore_fpu_checking function in arch/x86/include/asm/fpu-internal.h in the Linux kernel before 3.12.8 on the AMD K7 and K8 platforms does not clear pending exceptions before proceeding to an EMMS instruction, which allows local users to cause a denial of service or possibly gain privileges via a crafted application. The yam_ioctl function in drivers/net/hamradio/yam.c in the Linux kernel before 3.12.8 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability for an SIOCYAMGCFG ioctl call. The updated packages provides a solution for these security issues.
