Background ========== Subversion is an advanced version control system, similar to CVS, which supports additional functionality such as the ability to move, copy and delete files and directories. A Subversion server may be run as an Apache module, a standalone server (svnserve), or on-demand over ssh (a la CVS' ":ext:" protocol). The mod_authz_svn Apache module works with Subversion in Apache to limit access to parts of Subversion repositories based on policy set by the administrator. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-util/subversion <= 1.0.4-r1 >= 1.0.6 Description =========== Users with write access to part of a Subversion repository may bypass read restrictions on any part of that repository. This can be done using an "svn copy" command to copy the portion of a repository the user wishes to read into an area where they have write access. Since copies are versioned, any such copy attempts will be readily apparent. Impact ====== This is a low-risk vulnerability. It affects only users of Subversion who are running servers inside Apache and using mod_authz_svn. Additionally, this vulnerability may be exploited only by users with write access to some portion of a repository. Workaround ========== Keep sensitive content separated into different Subversion repositories, or disable the Apache Subversion server and use svnserve instead. Resolution ========== All Subversion users should upgrade to the latest available version: # emerge sync # emerge -pv ">=dev-util/subversion-1.0.6" # emerve ">=dev-util/subversion-1.0.6" References ========== [ 1 ] ChangeLog for Subversion 1.0.6 http://svn.collab.net/repos/svn/tags/1.0.6/CHANGES Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200407-20.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
