Subversion team reports :

The script contrib/hook-scripts/check-mime-type.pl does not escape argv arguments to โ€˜svnlookโ€™ that start with a hyphen. This could be used to cause โ€˜svnlookโ€™, and hence check-mime-type.pl, to error out.

The script contrib/hook-scripts/svn-keyword-check.pl parses filenames from the output of โ€˜svnlook changedโ€™ and passes them to a further shell command (equivalent to the โ€˜system()โ€™ call of the C standard library) without escaping them. This could be used to run arbitrary shell commands in the context of the user whom the pre-commit script runs as (the user who owns the repository).
