Synopsis: Moderate: subversion security update
Issue Date: 2011-06-08
CVE Numbers: CVE-2011-1752
 CVE-2011-1783
 CVE-2011-1921

Subversion (SVN) is a concurrent version control system which enables
one or more users to collaborate in developing and maintaining a
hierarchy of files and directories while keeping a history of all
changes. The mod_dav_svn module is used with the Apache HTTP Server to
allow access to Subversion repositories via HTTP.

An infinite loop flaw was found in the way the mod_dav_svn module
processed certain data sets. If the SVNPathAuthz directive was set to
"short_circuit", and path-based access control for files and directories
was enabled, a malicious, remote user could use this flaw to cause the
httpd process serving the request to consume an excessive amount of
system memory. (CVE-2011-1783)

A NULL pointer dereference flaw was found in the way the mod_dav_svn
module processed requests submitted against the URL of a baselined
resource. A malicious, remote user could use this flaw to cause the
httpd process serving the request to crash. (CVE-2011-1752)

An information disclosure flaw was found in the way the mod_dav_svn
module processed certain URLs when path-based access control for files
and directories was enabled. A malicious, remote user could possibly use
this flaw to access certain files in a repository that would otherwise
not be accessible to them. Note: This vulnerability cannot be triggered
if the SVNPathAuthz directive is set to "short_circuit". (CVE-2011-1921)

All Subversion users should upgrade to these updated packages, which
contain backported patches to correct these issues. After installing the
updated packages, you must restart the httpd daemon, if you are using
mod_dav_svn, for the update to take effect.
