Summary: Updated kernel packages that fix two security issues and two bugs are now available for Red Hat Enterprise Linux 4.7 Extended Update Support. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4.7.z - i386, ia64, noarch, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux ES version 4.7.z - i386, ia64, noarch, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. This update includes backported fixes for two approved security issues. These issues only affected users of Red Hat Enterprise Linux 4.7 Extended Update Support, as they have already been addressed for users of Red Hat Enterprise Linux 4 in the 4.8 update, RHSA-2009:1024. * the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important) * the Linux kernel implementation of the Network File System (NFS) version 4 did not properly initialize the file name limit in the nfs_server data structure. This flaw could possibly lead to a denial of service on a client mounting an NFSv4 share. (CVE-2009-1336, Moderate) This update fixes the following bugs: * on IBM System z systems, if the cio driver was used for DASD devices, and the last path to a DASD device was varied off, it was still possible to attempt read and write operations to that device, resulting in errors. In this update, path verification is used in this situation, which resolves this issue. Also, a bug may have caused errors when subchannels were unregistered. (BZ#437486) * a bug prevented the Broadcom NetXtreme II 57710 network device from working correctly on some Dell PowerEdge R805 systems. This device was correctly shown in "lspci" output, but "ifup" failed and an IP address was not assigned. In this update, the device works correctly on Dell PowerEdge R805 systems. (BZ#491752) Users should upgrade to these updated packages, which contain backported patches to correct these issues. For this update to take effect, the system must be rebooted. 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/): 491752 - For Broadcom(r) BMC57710, modprobe bnx2* fails citing memory allocation failures 493771 - CVE-2009-1337 kernel: exit_notify: kill the wrong capable(CAP_KILL) check 494074 - CVE-2009-1336 kernel: nfsv4 client can be crashed by stating a long filename 6.
