Insight

Insight

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. A NULL pointer dereference flaw was found in the way the mod_dav_svn module handled PROPFIND requests on activity URLs. A remote attacker could use this flaw to cause the httpd process serving the request to crash. (CVE-2013-1849) A flaw was found in the way the mod_dav_svn module handled large numbers of properties (such as those set with the 'svn propset' command). 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-2013-1845) Two NULL pointer dereference flaws were found in the way the mod_dav_svn module handled LOCK requests on certain types of URLs. A malicious, remote user could use these flaws to cause the httpd process serving the request to crash. (CVE-2013-1846, CVE-2013-1847) Note: The CVE-2013-1849, CVE-2013-1846, and CVE-2013-1847 issues only caused a temporary denial of service, as the Apache HTTP Server started a new process to replace the crashed child process. When using prefork MPM, the crash only affected the attacker. When using worker (threaded) MPM, the connections of other users may have been interrupted. Red Hat would like to thank the Apache Subversion project for reporting these issues. Upstream acknowledges Alexander Klink as the original reporter of CVE-2013-1845, Ben Reser as the original reporter of CVE-2013-1846, and Philip Martin and Ben Reser as the original reporters of CVE-2013-1847. 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.
