-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel-rt security and bug fix update Advisory ID: RHSA-2011:0500-01 Product: Red Hat Enterprise MRG for RHEL-5 Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0500.html Issue date: 2011-05-10 CVE Names: CVE-2011-0695 CVE-2011-0711 CVE-2011-0726 CVE-2011-1010 CVE-2011-1013 CVE-2011-1019 CVE-2011-1078 CVE-2011-1079 CVE-2011-1080 CVE-2011-1082 CVE-2011-1093 CVE-2011-1163 CVE-2011-1170 CVE-2011-1171 CVE-2011-1172 ===================================================================== 1. Summary: Updated kernel-rt packages that fix multiple security issues and various bugs are now available for Red Hat Enterprise MRG 1.3. 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: 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. This update fixes the following security issues: * A race condition in the way the Linux kernel's InfiniBand implementation set up new connections could allow a remote user to cause a denial of service. (CVE-2011-0695, 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) * 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 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) * A flaw in the Linux kernel's Event Poll (epoll) implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2011-1082, Moderate) * A missing initialization flaw in the XFS file system implementation could lead to an information leak. (CVE-2011-0711, 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 missing validation check in the Linux kernel's mac_partition() implementation, used for supporting file systems created on Mac OS operating systems, could allow a local attacker to cause a denial of service by mounting a disk that contains specially-crafted partitions. (CVE-2011-1010, 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 missing initialization flaw in sco_sock_getsockopt_old() could allow a local, unprivileged user to cause an information leak. (CVE-2011-1078, Low) * A buffer overflow flaw in the DEC Alpha OSF partition implementation in the Linux kernel could allow a local attacker to cause an information leak by mounting a disk that contains specially-crafted partition tables. (CVE-2011-1163, Low) * Missing validations of null-terminated string data structure elements in the do_replace(), compat_do_replace(), do_ipt_get_ctl(), do_ip6t_get_ctl(), and do_arpt_get_ctl() functions could allow a local user who has the CAP_NET_ADMIN capability to cause an information leak. (CVE-2011-1170, CVE-2011-1171, CVE-2011-1172, CVE-2011-1080, Low) Red Hat would like to thank Jens Kuehnel for reporting CVE-2011-0695; Vasiliy Kulikov for reporting CVE-2011-1079, CVE-2011-1019, CVE-2011-1078, CVE-2011-1170, CVE-2011-1171, CVE-2011-1172, and CVE-2011-1080; Nelson Elhage for reporting CVE-2011-1082; Dan Rosenberg for reporting CVE-2011-0711; Kees Cook for reporting CVE-2011-0726; and Timo Warns for reporting CVE-2011-1010 and CVE-2011-1163. This update also fixes various bugs. Documentation for these bug fixes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which upgrade the kernel-rt kernel to version 2.6.33.9-rt31, and 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 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.
