    Package        : scponly
    Vulnerability  : design error
    Problem type   : local
    Debian-specific: no
    CVE ID         : CVE-2005-4532
    Debian Bug     : 344418
    Max Vozeller discovered a vulnerability in scponly, a utility to
    restrict user commands to scp and sftp, that could lead to the
    execution of arbitray commands as root.  The system is only vulnerable
    if the program scponlyc is installed setuid root and if regular users
    have shell access to the machine.
    The old stable distribution (woody) does not contain an scponly package.
    For the stable distribution (sarge) this problem has been fixed in
    version 4.0-1sarge1.
    For the unstable distribution (sid) this problem has been fixed in
    version 4.6-1.
    We recommend that you upgrade your scponly package.
