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)
Red Hat would like to thank the Apache Subversion project for reporting
these issues. Upstream acknowledges Joe Schaefer of the Apache Software
Foundation as the original reporter of CVE-2011-1752; Ivan Zhakov of
VisualSVN as the original reporter of CVE-2011-1783; and Kamesh
Jayachandran of CollabNet, Inc. as the original reporter of 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.
