Problem description

CAN-2004-0749:
If a Subversion commit affects paths that an administrator has marked "unreadable" using mod_authz_svn, then

"svn log -v" will list the existence of the unreadable paths;
"svn log -v" will show the commit's log message, which might be considered sensitive metadata in some situations;
"svn propget" is also able to fetch the log message of any commit;
"svn blame" and other commands that follow renames are able to acknowledge the existence of earlier versions of files that exist at unreadable locations.

This security issue is not about revealing the contents of protected files: it only reveals metadata about protected areas such as paths and log messages. This may or may not be important to your organization, depending on how you're using path-based authorization, and the sensitivity of the metadata.
These issues only affects users of mod_authz_svn, not people using native httpd.conf directives (such as <Limit> or <LimitExcept>) directives to limit general readability on whole repositories.
