    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.
