Linux-Mandrake Security Update Advisory
 
Package name:           esound
Date:                   September 27th, 2000
Advisory ID:            MDKSA-2000:051
 
Affected versions:      6.0, 6.1, 7.0, 7.1


Problem Description:

A problem exists with the esound daemon, which is used in GNOME and responsible for multiplexing access to audio devices. Versions of esound prior to and including 0.2.19 create a world-writable directory in /tmp called .esd which is owned by the user running esound. This directory is used to store a unix domain socket. The socket is also created world-writable, so a race condition exists in the creation of this socket which allows a local attacker to cause an arbitrary file or directory owned by the user running esound to become world-writable. This update contains a patch from FreeBSD which creates ~/.esd as the temporary directory to use and makes the unix domain socket read and write only to the user.


Please verify these md5 checksums of the updates prior to upgrading to ensure the integrity of the downloaded package. You can do this by running the md5sum program on the downloaded package by using "md5sum package.rpm".

To upgrade automatically, use « MandrakeUpdate ».

If you want to upgrade manually, download the updated package from one of our FTP server mirrors and uprade with "rpm -Uvh package_name".

You can download the updates directly from:
ftp://ftp.linux.tucows.com/pub/distributions/Mandrake/Mandrake/updates
ftp://ftp.free.fr/pub/Distributions_Linux/Mandrake/updates

Or try one of the other mirrors listed at:

http://www.linux-mandrake.com/en/ftp.php3.

Updated packages are available in the "updates/[ver]/RPMS/" directory. For example, if you are looking for an updated RPM package for Linux-Mandrake 7.1, look for it in "updates/7.1/RPMS/". Updated source RPMs are available as well, but you generally do not need to download them.

Please be aware that sometimes it takes the mirrors a few hours to update, so if you want an immediate upgrade, please use one of the two above-listed mirrors.
