    Linux kernel (OMAP4) vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 10.10
    
    Summary:
    
    Several security issues were fixed in the kernel.
    
    Software Description:
    - linux-ti-omap4: Linux kernel for OMAP4
    
    Details:
    
    Aristide Fattori and Roberto Paleari reported a flaw in the Linux kernel's
    handling of IPv4 icmp packets. A remote user could exploit this to cause a
    denial of service. (CVE-2011-1927)
    
    Vegard Nossum discovered a leak in the kernel's inotify_init() system call.
    A local, unprivileged user could exploit this to cause a denial of service.
    (CVE-2010-4250)
    
    An error was discovered in the kernel's handling of CUSE (Character device
    in Userspace). A local attacker might exploit this flaw to escalate
    privilege, if access to /dev/cuse has been modified to allow non-root
    users. (CVE-2010-4650)
    
    A flaw was found in the kernel's Integrity Measurement Architecture (IMA).
    Changes made by an attacker might not be discovered by IMA, if SELinux was
    disabled, and a new IMA rule was loaded. (CVE-2011-0006)
    
    A flaw was found in the Linux Ethernet bridge's handling of IGMP (Internet
    Group Management Protocol) packets. An unprivileged local user could
    exploit this flaw to crash the system. (CVE-2011-0716)
    
    Dan Rosenberg reported errors in the OSS (Open Sound System) MIDI
    interface. A local attacker on non-x86 systems might be able to cause a
    denial of service. (CVE-2011-1476)
    
    Dan Rosenberg reported errors in the kernel's OSS (Open Sound System)
    driver for Yamaha FM synthesizer chips. A local user can exploit this to
    cause memory corruption, causing a denial of service or privilege
    escalation. (CVE-2011-1477)
    
    Dan Rosenberg reported an error in the old ABI compatibility layer of ARM
    kernels. A local attacker could exploit this flaw to cause a denial of
    service or gain root privileges. (CVE-2011-1759)
    
    Ben Hutchings reported a flaw in the kernel's handling of corrupt LDM
    partitions. A local user could exploit this to cause a denial of service or
    escalate privileges. (CVE-2011-2182)
    
    A flaw was discovered in the Linux kernel's AppArmor security interface
    when invalid information was written to it. An unprivileged local user
    could use this to cause a denial of service on the system. (CVE-2011-3619)
    
    It was discovered that some import kernel threads can be blocked by a user
    level process. An unprivileged local user could exploit this flaw to cause
    a denial of service. (CVE-2011-4621)
    
    A flaw was discovered in the XFS filesystem. If a local user mounts a
    specially crafted XFS image it could potential execute arbitrary code on
    the system. (CVE-2012-0038)
    
    Chen Haogang discovered an integer overflow that could result in memory
    corruption. A local unprivileged user could use this to crash the system.
    (CVE-2012-0044)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 10.10:
      linux-image-2.6.35-903-omap4    2.6.35-903.32
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
