-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2014:1971-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-1971.html Issue date: 2014-12-09 CVE Names: CVE-2013-2929 CVE-2014-1739 CVE-2014-3181 CVE-2014-3182 CVE-2014-3184 CVE-2014-3185 CVE-2014-3186 CVE-2014-3631 CVE-2014-3673 CVE-2014-3687 CVE-2014-3688 CVE-2014-4027 CVE-2014-4652 CVE-2014-4654 CVE-2014-4655 CVE-2014-4656 CVE-2014-5045 CVE-2014-6410 ===================================================================== 1. Summary: Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 7. Red Hat Product Security 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. The kernel packages contain the Linux kernel, the core of any Linux operating system. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - noarch, x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - noarch, x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 7) - noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - noarch, x86_64 3. Description: * A flaw was found in the way the Linux kernel's SCTP implementation handled malformed or duplicate Address Configuration Change Chunks (ASCONF). A remote attacker could use either of these flaws to crash the system. (CVE-2014-3673, CVE-2014-3687, Important) * A flaw was found in the way the Linux kernel's SCTP implementation handled the association's output queue. A remote attacker could send specially crafted packets that would cause the system to use an excessive amount of memory, leading to a denial of service. (CVE-2014-3688, Important) * Two flaws were found in the way the Apple Magic Mouse/Trackpad multi-touch driver and the Minibox PicoLCD driver handled invalid HID reports. An attacker with physical access to the system could use these flaws to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-3181, CVE-2014-3186, Moderate) * A memory corruption flaw was found in the way the USB ConnectTech WhiteHEAT serial driver processed completion commands sent via USB Request Blocks buffers. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-3185, Moderate) * A flaw was found in the way the Linux kernel's keys subsystem handled the termination condition in the associative array garbage collection functionality. A local, unprivileged user could use this flaw to crash the system. (CVE-2014-3631, Moderate) * Multiple flaws were found in the way the Linux kernel's ALSA implementation handled user controls. A local, privileged user could use either of these flaws to crash the system. (CVE-2014-4654, CVE-2014-4655, CVE-2014-4656, Moderate) * A flaw was found in the way the Linux kernel's VFS subsystem handled reference counting when performing unmount operations on symbolic links. A local, unprivileged user could use this flaw to exhaust all available memory on the system or, potentially, trigger a use-after-free error, resulting in a system crash or privilege escalation. (CVE-2014-5045, Moderate) * A flaw was found in the way the get_dumpable() function return value was interpreted in the ptrace subsystem of the Linux kernel. When 'fs.suid_dumpable' was set to 2, a local, unprivileged local user could use this flaw to bypass intended ptrace restrictions and obtain potentially sensitive information. (CVE-2013-2929, Low) * A stack overflow flaw caused by infinite recursion was found in the way the Linux kernel's UDF file system implementation processed indirect ICBs. An attacker with physical access to the system could use a specially crafted UDF image to crash the system. (CVE-2014-6410, Low) * An information leak flaw in the way the Linux kernel handled media device enumerate entities IOCTL requests could allow a local user able to access the /dev/media0 device file to leak kernel memory bytes. (CVE-2014-1739, Low) * An out-of-bounds read flaw in the Logitech Unifying receiver driver could allow an attacker with physical access to the system to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-3182, Low) * Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled invalid HID reports. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer. (CVE-2014-3184, Low) * An information leak flaw was found in the RAM Disks Memory Copy (rd_mcp) back end driver of the iSCSI Target subsystem could allow a privileged user to leak the contents of kernel memory to an iSCSI initiator remote client. (CVE-2014-4027, Low) * An information leak flaw in the Linux kernel's ALSA implementation could allow a local, privileged user to leak kernel memory to user space. (CVE-2014-4652, Low) 4. Solution: Red Hat would like to thank Frey Alfredsson for reporting CVE-2014-3631, and Vasily Averin of Parallels for reporting CVE-2014-5045. The CVE-2014-3673 was discovered by Liu Wei of Red Hat. All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect. 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/articles/11258 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.
