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
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
You can download the updates directly from:
Or try one of the other mirrors listed at:
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.
