Detail
Problem Description: Updated kernel packages that fix one security issue and four bugs are now available for Red Hat Enterprise Linux 5.4 Extended Update Support. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5.4.z server) - i386, ia64, noarch, ppc, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue: * Buffer overflow flaws were found in the Linux kernel's implementation of the server-side External Data Representation (XDR) for the Network File System (NFS) version 4. An attacker on the local network could send a specially-crafted large compound request to the NFSv4 server, which could possibly result in a kernel panic (denial of service) or, potentially, code execution. (CVE-2010-2521, Important) This update also fixes the following bugs: * A race condition existed when generating new process IDs with the result that the wrong process could have been signaled or killed accidentally, leading to various application faults. This update detects and disallows the reuse of PID numbers. (BZ#638865) * In a two node cluster, moving 100 files between two folders using the lock master was nearly instantaneous. However, not using the lock master resulted in considerably worse performance on both GFS1 (Global File System 1) and GFS2 (Global File System 2) file systems. With this update, not using the lock master does not lead to worsened performance on either of the aforementioned file systems. (BZ#639071) * The device naming changed after additional devices were added to the system and caused various problems. With this update, device naming remains constant after adding any additional devices. (BZ#646764) * On some bnx2-based devices, frames could drop unexpectedly. This was shown by the increasing "rx_fw_discards" values in the "ethtool Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the 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 To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system. 5. Bugs fixed (http://bugzilla.redhat.com/): 612028 - CVE-2010-2521 kernel: nfsd4: bug in read_buf 638865 - [5.5] a race in pid generation that causes pids to be reused immediately. [rhel-5.4.z] 639071 - GFS1 vs GFS2 performance issue [rhel-5.4.z] 646764 - RHEL5.6 Include DL580 G7 in bfsort whitelist [rhel-5.4.z] 649254 - bnx2 adapter periodically dropping received packets [rhel-5.4.z] |

Description: | Multiple buffer overflows in fs/nfsd/nfs4xdr.c in the XDR implementation in the NFS server in the Linux kernel before 2.6.34-rc6 allow remote attackers to cause a denial of service (panic) or possibly execute arbitrary code via a crafted NFSv4 compound WRITE request, related to the read_buf and nfsd4_decode_compound functions. | ||
