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.
