Debian DSA-1505-1 : alsa-driver - kernel memory leak

low Nessus Plugin ID 31149
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

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 ).

Solution

Upgrade the alsa-driver and alsa-modules-i386 packages.

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 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.
