MDVA-2008:168 : sound-scripts

high Nessus Plugin ID 37144

Synopsis

The remote Mandriva host is missing one or more security-related patches.

Description

The sound initialization scripts provided with Mandriva Linux 2009 activate the Analog Loopback channel when it is present. This channel is present on most audio chipsets supported by the snd-hda-intel driver, which are commonly used on recent systems. When active, this channel plays back the sound received by the line-in and mic-in channels. If nothing is actually connected to these channels, this can result in an unpleasant loud noise over the speakers or headphones connected to the line-out or speaker-out connector.

This update adjusts the sound initialization scripts to mute this channel by default. Unfortunately, this change will not be applied automatically on already-installed systems, as existing settings are automatically stored at shutdown and re-applied at startup on Mandriva Linux. If you are suffering from this issue, then you can run the command 'reset_sound' as root after installing this update, and it should resolve the issue. Alternatively, you can simply disable / mute the Analog Loopback channel yourself, using a mixer application.

Solution

Update the affected package(s).
