Joachim Breitner discovered that Subversion support in scponly is inherently insecure, allowing execution of arbitrary commands. Further investigation showed that rsync and Unison support suffer from similar issues. This set of issues has been assigned CVE-2007-6350.
In addition, it was discovered that it was possible to invoke scp with certain options that may lead to the execution of arbitrary commands (CVE-2007-6415 ).
This update removes Subversion, rsync and Unison support from the scponly package, and prevents scp from being invoked with the dangerous options.
