Package        : alsa-driver
Vulnerability  : kernel memory leak
Problem type   : local
Debian-specific: no
CVE Id(s)      : CVE-2007-4571

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.
