The remote host is affected by the vulnerability described in GLSA-201309-11 (Subversion: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Subversion. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could cause a Denial of Service condition or obtain       sensitive information. A local attacker could escalate his privileges to       the user running svnserve.
  Workaround :

    There is no known workaround at this time.

Updated subversion packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several vulnerabilities were discovered in Subversion, a version control system. The Common Vulnerabilities and Exposures project identifies the following problems :

CVE-2015-0248

Subversion mod_dav_svn and svnserve were vulnerable to a remotely triggerable assertion DoS vulnerability for certain requests with dynamically evaluated revision numbers.

CVE-2015-0251

Subversion HTTP servers allow spoofing svn:author property values for new revisions via specially crafted v1 HTTP protocol request sequences.

CVE-2013-1845

Subversion mod_dav_svn was vulnerable to a denial of service attack through a remotely triggered memory exhaustion.

CVE-2013-1846 / CVE-2013-1847 / CVE-2013-1849 / CVE-2014-0032

Subversion mod_dav_svn was vulnerable to multiple remotely triggered crashes.

This update has been prepared by James McCoy.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple vulnerabilities has been found and corrected in subversion :

Subversion's mod_dav_svn Apache HTTPD server module will use excessive amounts of memory when a large number of properties are set or deleted on a node. This can lead to a DoS. There are no known instances of this problem being observed in the wild (CVE-2013-1845).

Subversion's mod_dav_svn Apache HTTPD server module will crash when a LOCK request is made against activity URLs. This can lead to a DoS.
There are no known instances of this problem being observed in the wild (CVE-2013-1846).

Subversion's mod_dav_svn Apache HTTPD server module will crash in some circumstances when a LOCK request is made against a non-existent URL.
This can lead to a DoS. There are no known instances of this problem being observed in the wild (CVE-2013-1847).

Subversion's mod_dav_svn Apache HTTPD server module will crash when a PROPFIND request is made against activity URLs. This can lead to a DoS. There are no known instances of this problem being observed in the wild, but the details of how to exploit it have been disclosed on the full disclosure mailing list (CVE-2013-1849).

Subversion's mod_dav_svn Apache HTTPD server module will crash when a log REPORT request receives a limit that is out of the allowed range.
This can lead to a DoS. There are no known instances of this problem being used as a DoS in the wild (CVE-2013-1884).

The updated packages have been upgraded to the 1.7.9 version which is not affected by these issues.

The version of Apache Subversion Server installed on the remote host is prior to 1.6.21 or 1.7.x prior to 1.7.9. It is, therefore, affected by multiple denial of service (DoS) vulnerabilities in the 'mod_dav_svn' Apache HTTPD server module :

  - A flaw exists in 'mod_dav_svn' that is triggered when     handling node properties. (CVE-2013-1845)

  - A NULL pointer dereference exists in the 'mod_dav_svn'     module, triggered during the handling of a crafted Log     REPORT request, URL lock request, LOCK request against     non-existent URL, or URL PROPFIND request.
    (CVE-2013-1846, CVE-2013-1847, CVE-2013-1849)

  - A NULL pointer dereference exists in the 'mod_dav_svn'     module, triggered during the handling of a crafted Log     REPORT request. This flaw reportedly affects Apache     Subversion 1.7.x only.  (CVE-2013-1884)

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.
