Detail
Problem Description: Updated kernel-rt packages that fix security issues, two bugs, and add two enhancements are now available for Red Hat Enterprise MRG 1.2. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: MRG Realtime for RHEL 5 Server - i386, noarch, x86_64 3. Description: The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. These updated packages fix the following security issues: * a NULL pointer dereference flaw was found in the NFSv4 implementation in the Linux kernel. Several of the NFSv4 file locking functions failed to check whether a file had been opened on the server before performing locking operations on it. A local user on a system with an NFSv4 share mounted could possibly use this flaw to cause a denial of service or escalate their privileges. (CVE-2009-3726, Important) * permission issues were found in the megaraid_sas driver (for SAS based RAID controllers) in the Linux kernel. The "dbg_lvl" and "poll_mode_io" files on the sysfs file system ("/sys/") had world-writable permissions. This could allow local, unprivileged users to change the behavior of the driver. (CVE-2009-3889, CVE-2009-3939, Moderate) These updated packages also fix the following bugs: * a problem existed with the i5000_edac driver under some topologies. In some cases, this driver failed to export memory devices via sysfs, preventing the ibm-prtm service from starting. With this update, the memory devices are accessible, allowing the ibm-prtm service to start, and therefore perform SMI remediation as expected. (BZ#527421) * the "/proc/sys/vm/mmap_min_addr" tunable helps prevent unprivileged users from creating new memory mappings below the minimum address. The sysctl value for mmap_min_addr could be changed by a process or user that has an effective user ID (euid) of 0, even if the process or user does not have the CAP_SYS_RAWIO capability. This update adds a capability check for the CAP_SYS_RAWIO capability before allowing the mmap_min_addr value to be changed. (BZ#534019) As well, these updated packages add the following enhancements: * the Intel ixgbe driver was updated to upstream version 2.0.16-k2. (BZ#537505) * the InfiniBand OFED driver was updated to upstream version 1.4.1. (BZ#537500) Users should upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. The system must be rebooted for this update to take effect. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 526068 - CVE-2009-3889 CVE-2009-3939 kernel: megaraid_sas permissions in sysfs 527421 - HS21xm i5000_edac kernel topology fix 529227 - CVE-2009-3726 kernel: nfsv4: kernel panic in nfs4_proc_lock() 534019 - kernel: sysctl: require CAP_SYS_RAWIO to set mmap_min_addr [mrg-1] 537500 - Update Infiniband system to OFED 1.4.1 537505 - update Intel ixgbe driver to latest upstream version |

Description: | The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state. | ||
