Debian Security Advisory DSA-2063-1                  security () debian org

Package        : pmount
Vulnerability  : insecure temporary file
Problem type   : local
Debian-specific: no
CVE Id         : CVE-2010-2192


Dan Rosenberg discovered that pmount, a wrapper around the standard mount
program which permits normal users to mount removable devices without a
matching /etc/fstab entry, creates files in /var/lock insecurely.
A local attacker could overwrite arbitrary files utilising a symlink attack.


For the stable distribution (lenny), this problem has been fixed in
version 0.9.18-2+lenny1

For the unstable distribution (sid), this problem has been fixed in
version 0.9.23-1, and will migrate to the testing distribution (squeeze)
shortly.

We recommend that you upgrade your pmount package.

Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
