(scponly: Multiple vulnerabilities)

    Joachim Breitner reported that Subversion and rsync support invokes
    subcommands in an insecure manner (CVE-2007-6350). It has also been
    discovered that scponly does not filter the -o and -F options to the
    scp executable (CVE-2007-6415).
  
Impact :

    A local attacker could exploit these vulnerabilities to elevate
    privileges and execute arbitrary commands on the vulnerable host.
  
Workaround :

    There is no known workaround at this time."

"All scponly users should upgrade to the latest version:
    # emerge --sync

    Due to the design of scponly's Subversion support, security
    restrictions can still be circumvented. Please read carefully the
    SECURITY file included in the package."
