-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel security, bug fix, and enhancement update Advisory ID: RHSA-2011:0498-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0498.html Issue date: 2011-05-10 CVE Names: CVE-2010-4250 CVE-2010-4565 CVE-2010-4649 CVE-2011-0006 CVE-2011-0711 CVE-2011-0712 CVE-2011-0726 CVE-2011-1013 CVE-2011-1016 CVE-2011-1019 CVE-2011-1044 CVE-2011-1079 CVE-2011-1080 CVE-2011-1093 CVE-2011-1573 ===================================================================== 1. Summary: Updated kernel packages that fix several security issues, various bugs, and add an enhancement are now available for Red Hat Enterprise Linux 6. 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes: * An integer overflow flaw in ib_uverbs_poll_cq() could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2010-4649, Important) * An integer signedness flaw in drm_modeset_ctl() could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2011-1013, Important) * The Radeon GPU drivers in the Linux kernel were missing sanity checks for the Anti Aliasing (AA) resolve register values which could allow a local, unprivileged user to cause a denial of service or escalate their privileges on systems using a graphics card from the ATI Radeon R300, R400, or R500 family of cards. (CVE-2011-1016, Important) * A flaw in dccp_rcv_state_process() could allow a remote attacker to cause a denial of service, even when the socket was already closed. (CVE-2011-1093, Important) * A flaw in the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation could allow a remote attacker to cause a denial of service if the sysctl "net.sctp.addip_enable" and "auth_enable" variables were turned on (they are off by default). (CVE-2011-1573, Important) * A memory leak in the inotify_init() system call. In some cases, it could leak a group, which could allow a local, unprivileged user to eventually cause a denial of service. (CVE-2010-4250, Moderate) * A missing validation of a null-terminated string data structure element in bnep_sock_ioctl() could allow a local user to cause an information leak or a denial of service. (CVE-2011-1079, Moderate) * An information leak in bcm_connect() in the Controller Area Network (CAN) Broadcast Manager implementation could allow a local, unprivileged user to leak kernel mode addresses in "/proc/net/can-bcm". (CVE-2010-4565, Low) * A flaw was found in the Linux kernel's Integrity Measurement Architecture (IMA) implementation. When SELinux was disabled, adding an IMA rule which was supposed to be processed by SELinux would cause ima_match_rules() to always succeed, ignoring any remaining rules. (CVE-2011-0006, Low) * A missing initialization flaw in the XFS file system implementation could lead to an information leak. (CVE-2011-0711, Low) * Buffer overflow flaws in snd_usb_caiaq_audio_init() and snd_usb_caiaq_midi_init() could allow a local, unprivileged user with access to a Native Instruments USB audio device to cause a denial of service or escalate their privileges. (CVE-2011-0712, Low) * The start_code and end_code values in "/proc/[pid]/stat" were not protected. In certain scenarios, this flaw could be used to defeat Address Space Layout Randomization (ASLR). (CVE-2011-0726, Low) * A flaw in dev_load() could allow a local user who has the CAP_NET_ADMIN capability to load arbitrary modules from "/lib/modules/", instead of only netdev modules. (CVE-2011-1019, Low) * A flaw in ib_uverbs_poll_cq() could allow a local, unprivileged user to cause an information leak. (CVE-2011-1044, Low) * A missing validation of a null-terminated string data structure element in do_replace() could allow a local user who has the CAP_NET_ADMIN capability to cause an information leak. (CVE-2011-1080, Low) Red Hat would like to thank Vegard Nossum for reporting CVE-2010-4250; Vasiliy Kulikov for reporting CVE-2011-1079, CVE-2011-1019, and CVE-2011-1080; Dan Rosenberg for reporting CVE-2010-4565 and CVE-2011-0711; Rafael Dominguez Vega for reporting CVE-2011-0712; and Kees Cook for reporting CVE-2011-0726. This update also fixes various bugs and adds an enhancement. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which contain backported patches to resolve these issues, and fix the bugs and add the enhancement noted in the Technical Notes. 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 https://access.redhat.com/kb/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.
