    - Ubuntu 10.10
    
    Summary:
    
    Several security issues were fixed in the kernel.
    
    Software Description:
    - linux-ti-omap4: Linux kernel for OMAP4
    
    Details:
    
    Peter Huewe discovered an information leak in the handling of reading
    security-related TPM data. A local, unprivileged user could read the
    results of a previous TPM command. (CVE-2011-1162)
    
    Clement Lecigne discovered a bug in the HFS filesystem. A local attacker
    could exploit this to cause a kernel oops. (CVE-2011-2203)
    
    Han-Wen Nienhuys reported a flaw in the FUSE kernel module. A local user
    who can mount a FUSE file system could cause a denial of service.
    (CVE-2011-3353)
    
    A flaw was found in the b43 driver in the Linux kernel. An attacker could
    use this flaw to cause a denial of service if the system has an active
    wireless interface using the b43 driver. (CVE-2011-3359)
    
    A flaw was found in how the Linux kernel handles user-defined key types. An
    unprivileged local user could exploit this to crash the system.
    (CVE-2011-4110)
    
    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    2.6.35-903.29
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
