Detail

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.

Title: The snd_mem_proc_read function in sound/core/memalloc.c in the Advanced Linux Sound Architecture (ALSA) in the Linux kernel before 2.6.22.8 does not return the correct write size, which allows local users to obtain sensitive information (kernel memory contents) via a small count argument, as demonstrated by multiple reads of /proc/driver/snd-page-alloc.
