Integer overflow in the xfs_acl_from_disk function in fs/xfs/xfs_acl.c in the Linux kernel before 3.1.9 allows local users to cause a denial of service (panic) via a filesystem with a malformed ACL, leading to a heap-based buffer overflow.

Updated kernel-rt packages that fix multiple security issues and various bugs are now available for Red Hat Enterprise MRG 2.1.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

These packages contain the Linux kernel.

Security fixes :

* SG_IO ioctl SCSI requests on partitions or LVM volumes could be passed to the underlying block device, allowing a privileged user to bypass restrictions and gain read and write access (and be able to issue other SCSI commands) to the entire block device. (CVE-2011-4127, Important)

* A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. (CVE-2012-0044, Important)

* A local, unprivileged user could use a flaw in the Performance Events implementation to cause a denial of service. (CVE-2011-2918, Moderate)

* A local, unprivileged user could use flaws in the XFS file system implementation to cause a denial of service or escalate their privileges by mounting a specially crafted disk. (CVE-2011-4077, CVE-2012-0038, Moderate)

* A local, unprivileged user could use a flaw in the Out of Memory (OOM) killer to monopolize memory, have their process skipped by the OOM killer, or cause other tasks to be terminated. (CVE-2011-4097, Moderate)

* A local, unprivileged user could use a flaw in the key management facility to cause a denial of service. (CVE-2011-4110, Moderate)

* A malicious Network File System version 4 (NFSv4) server could return a crafted reply to a GETACL request, causing a denial of service on the client. (CVE-2011-4131, Moderate)

* A local attacker could use a flaw in the Journaling Block Device (JBD) to crash the system by mounting a specially crafted ext3 or ext4 disk. (CVE-2011-4132, Moderate)

* A flaw in igmp_heard_query() could allow an attacker, who is able to send certain IGMP (Internet Group Management Protocol) packets to a target system, to cause a denial of service. (CVE-2012-0207, Moderate)

* If lock contention during signal sending occurred when in a software interrupt handler that is using the per-CPU debug stack, the task could be scheduled out on the realtime kernel, possibly leading to debug stack corruption. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-0810, Moderate)

Bug fixes :

* When a sleeping task, waiting on a futex (fast userspace mutex), tried to get the spin_lock(hb->lock) RT-mutex, if the owner of the futex released the lock, the sleeping task was put on a futex proxy lock. Consequently, the sleeping task was blocked on two locks and eventually terminated in the BUG_ON() function. With this update, the WAKEUP_INPROGRESS pseudo-lock has been added to be used as a proxy lock. This pseudo-lock tells the sleeping task that it is being woken up so that the task no longer tries to get the second lock. Now, the futex code works as expected and sleeping tasks no longer crash in the described scenario. (BZ#784733)

* When the CONFIG_CRYPTO_FIPS configuration option was disabled, some services such as sshd and ipsec, while working properly, returned warning messages regarding this missing option during start up. With this update, CONFIG_CRYPTO_FIPS has been enabled and no warning messages are now returned in the described scenario. (BZ#786145)

* Previously, when a read operation on a loop device failed, the data successfully read from the device was not cleared and could eventually leak. This bug has been fixed and all data are now properly cleared in the described scenario. (BZ#761420)

* Due to an assembler-sourced object, the perf utility (from the perf-rt package) for AMD64 and Intel 64 architectures contained an executable stack. This update adds the '.note.GNU-stack' section definition to the bench/mem-memcpy-x86-64-asm.S component of perf, with all flags disabled, and perf no longer contains an executable stack, thus fixing this bug. (BZ#783570)

Updated kernel packages that fix various security issues and several bugs are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

* A buffer overflow flaw was found in the way the Linux kernel's XFS file system implementation handled links with overly long path names.
A local, unprivileged user could use this flaw to cause a denial of service or escalate their privileges by mounting a specially crafted disk. (CVE-2011-4077, Moderate)

* Flaws in ghash_update() and ghash_final() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-4081, Moderate)

* A flaw was found in the Linux kernel's Journaling Block Device (JBD). A local, unprivileged user could use this flaw to crash the system by mounting a specially crafted ext3 or ext4 disk.
(CVE-2011-4132, Moderate)

* It was found that the kvm_vm_ioctl_assign_device() function in the KVM (Kernel-based Virtual Machine) subsystem of a Linux kernel did not check if the user requesting device assignment was privileged or not.
A local, unprivileged user on the host could assign unused PCI devices, or even devices that were in use and whose resources were not properly claimed by the respective drivers, which could result in the host crashing. (CVE-2011-4347, Moderate)

* Two flaws were found in the way the Linux kernel's __sys_sendmsg() function, when invoked via the sendmmsg() system call, accessed user-space memory. A local, unprivileged user could use these flaws to cause a denial of service. (CVE-2011-4594, Moderate)

* The RHSA-2011:1530 kernel update introduced an integer overflow flaw in the Linux kernel. On PowerPC systems, a local, unprivileged user could use this flaw to cause a denial of service. (CVE-2011-4611, Moderate)

* A flaw was found in the way the KVM subsystem of a Linux kernel handled PIT (Programmable Interval Timer) IRQs (interrupt requests) when there was no virtual interrupt controller set up. A local, unprivileged user on the host could force this situation to occur, resulting in the host crashing. (CVE-2011-4622, Moderate)

* A flaw was found in the way the Linux kernel's XFS file system implementation handled on-disk Access Control Lists (ACLs). A local, unprivileged user could use this flaw to cause a denial of service or escalate their privileges by mounting a specially crafted disk.
(CVE-2012-0038, Moderate)

* A flaw was found in the way the Linux kernel's KVM hypervisor implementation emulated the syscall instruction for 32-bit guests. An unprivileged guest user could trigger this flaw to crash the guest.
(CVE-2012-0045, Moderate)

* A divide-by-zero flaw was found in the Linux kernel's igmp_heard_query() function. An attacker able to send certain IGMP (Internet Group Management Protocol) packets to a target system could use this flaw to cause a denial of service. (CVE-2012-0207, Moderate)
