    linux-ti-omap4 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Several security issues were fixed in the kernel.
    
    Software Description:
    - linux-ti-omap4: Linux kernel for OMAP4
    
    Details:
    
    Kees Cook discovered a flaw in the Linux kernel's iSCSI subsystem. A remote
    unauthenticated attacker could exploit this flaw to cause a denial of
    service (system crash) or potentially gain administrative privileges.
    (CVE-2013-2850)
    
    An information leak was discovered in the Linux kernel when inotify is used
    to monitor the /dev/ptmx device. A local user could exploit this flaw to
    discover keystroke timing and potentially discover sensitive information
    like password length. (CVE-2013-0160)
    
    A flaw was discovered in the Linux kernel's perf events subsystem for Intel
    Sandy Bridge and Ivy Bridge processors. A local user could exploit this
    flaw to cause a denial of service (system crash). (CVE-2013-2146)
    
    An information leak was discovered in the Linux kernel's crypto API. A
    local user could exploit this flaw to examine potentially sensitive
    information from the kernel's stack memory. (CVE-2013-3076)
    
    An information leak was discovered in the Linux kernel's rcvmsg path for
    ATM (Asynchronous Transfer Mode). A local user could exploit this flaw to
    examine potentially sensitive information from the kernel's stack memory.
    (CVE-2013-3222)
    
    An information leak was discovered in the Linux kernel's recvmsg path for
    ax25 address family. A local user could exploit this flaw to examine
    potentially sensitive information from the kernel's stack memory.
    (CVE-2013-3223)
    
    An information leak was discovered in the Linux kernel's recvmsg path for
    the bluetooth address family. A local user could exploit this flaw to
    examine potentially sensitive information from the kernel's stack memory.
    (CVE-2013-3224)
    
    An information leak was discovered in the Linux kernel's bluetooth rfcomm
    protocol support. A local user could exploit this flaw to examine
    potentially sensitive information from the kernel's stack memory.
    (CVE-2013-3225)
    
    An information leak was discovered in the Linux kernel's CAIF protocol
    implementation. A local user could exploit this flaw to examine potentially
    sensitive information from the kernel's stack memory. (CVE-2013-3227)
    
    An information leak was discovered in the Linux kernel's IRDA (infrared)
    support subsystem. A local user could exploit this flaw to examine
    potentially sensitive information from the kernel's stack memory.
    (CVE-2013-3228)
    
    An information leak was discovered in the Linux kernel's s390 - z/VM
    support. A local user could exploit this flaw to examine potentially
    sensitive information from the kernel's stack memory. (CVE-2013-3229)
    
    An information leak was discovered in the Linux kernel's llc (Logical Link
    Layer 2) support. A local user could exploit this flaw to examine
    potentially sensitive information from the kernel's stack memory.
    (CVE-2013-3231)
    
    An information leak was discovered in the Linux kernel's receive message
    handling for the netrom address family. A local user could exploit this
    flaw to obtain sensitive information from the kernel's stack memory.
    (CVE-2013-3232)
    
    An information leak was discovered in the Linux kernel's Rose X.25 protocol
    layer. A local user could exploit this flaw to examine potentially
    sensitive information from the kernel's stack memory. (CVE-2013-3234)
    
    An information leak was discovered in the Linux kernel's TIPC (Transparent
    Inter Process Communication) protocol implementation. A local user could
    exploit this flaw to examine potentially sensitive information from the
    kernel's stack memory. (CVE-2013-3235)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      linux-image-3.2.0-1433-omap4    3.2.0-1433.44
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
    
    ATTENTION: Due to an unavoidable ABI change the kernel updates have
    been given a new version number, which requires you to recompile and
    reinstall all third party kernel modules you might have installed. If
    you use linux-restricted-modules, you have to update that package as
    well to get modules which work with the new kernel version. Unless you
    manually uninstalled the standard kernel metapackages (e.g. linux-generic,
    linux-server, linux-powerpc), a standard system upgrade will automatically
    perform this as well.
