    Takashi Iwai supplied a fix for a memory leak in the snd_page_alloc module.
    Local users could exploit this issue to obtain sensitive information from
    the kernel (CVE-2007-4571).
    
    For the stable distribution (etch), this problem has been fixed in
    version 1.0.13-5etch1. This issue was already fixed for the version
    of ALSA provided by linux-2.6 in DSA 1479.
    
    For the oldstable distribution (sarge), this problem has been fixed in
    version 1.0.8-7sarge1. The prebuilt modules provided by alsa-modules-i386
    have been rebuilt to take advantage of this update, and are available in
    version 1.0.8+2sarge2.
    
    For the unstable distributions (sid), this problem was fixed in version
    1.0.15-1.
    
    We recommend that you upgrade your alsa-driver and alsa-modules-i386
    packages.
    
    Upgrade instructions
    - --------------------
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    
    The prebuilt modules update coincides with an ABI change in the 2.4.27
    kernel in oldstable (see DSA 1503). If you are using the prebuilt modules
    provided by one of the alsa-modules-i386 packages, you will need to update
    your kernel to the new ABI before you can use the updated version of that
    package. For more information about Debian kernel ABI changes, see:
      http://wiki.debian.org/DebianKernelABIChanges
    
    Any modules manually built from the alsa-source package will need to be
    rebuilt against the updated alsa-source package to inherit this fix.
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.
