    Package        : fdclone
    Vulnerability  : insecure temporary directory
    Problem-Type   : local
    Debian-specific: no
    CVE Ids        : CAN-2003-0596
    
    fdclone creates a temporary directory in /tmp as a workspace.
    However, if this directory already exists, the existing directory is
    used instead, regardless of its ownership or permissions.  This would
    allow an attacker to gain access to fdclone's temporary files and
    their contents, or replace them with other files under the attacker's
    control.
    
    For the stable distribution (woody) this problem has been fixed in
    version 2.00a-1woody3.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 2.04-1.
    
    We recommend that you update your fdclone package.
