This update of subversion fixes two potential DoS vulnerabilities (bug#821505, CVE-2013-1968 / CVE-2013-2112).

  - Server-side bugfixes :

  - fix FSFS repository corruption due to newline in     filename (issue #4340)

  - fix svnserve exiting when a client connection is aborted     (r1482759)

  - Other tool improvements and bugfixes :

  - fix argument processing in contrib hook scripts     (r1485350)

This update includes the latest release of Apache Subversion 1.7, version 1.7.11. Several security vulnerabilities are fixed in this update :

Subversion's mod_dav_svn Apache HTTPD server module will trigger an assertion on some requests made against a revision root. This can lead to a DoS. If assertions are disabled it will trigger a read overflow which may cause a segmentation fault or undefined behavior. Commit access is required to exploit this. (CVE-2013-4131)

If a filename which contains a newline character (ASCII 0x0a) is committed to a repository using the FSFS format, the resulting revision is corrupt. This can lead to disruption for users of the repository. (CVE-2013-1968)

Subversion's contrib/ directory contains two example hook scripts, which use 'svnlook changed' to examine a revision or transaction and then pass those paths as arguments to further 'svnlook' commands, without properly escaping the command-line. (CVE-2013-2088)

Subversion's svnserve server process may exit when an incoming TCP connection is closed early in the connection process. This can lead to disruption for users of the server. (CVE-2013-2112)

The following client-side bugs were fixed in the 1.7.10 release :

  - fix 'svn revert' 'no such table: revert_list' spurious     error

    - fix 'svn diff' doesn't show some locally added files

    - fix changelist filtering when --changelist values       aren't UTF8

    - fix 'svn diff --git' shows wrong copyfrom

    - fix 'svn diff -x-w' shows wrong changes

    - fix 'svn blame' sometimes shows every line as modified

    - fix regression in 'svn status -u' output for externals

    - fix file permissions change on commit of file with       keywords

    - improve some fatal error messages

    - fix externals not removed when working copy is made       shallow

The following server-side bugs are fixed :

  - fix repository corruption due to newline in filename

    - fix svnserve exiting when a client connection is       aborted

    - fix svnserve memory use after clear

Alexander Klink discovered that the Subversion mod_dav_svn module for Apache did not properly handle a large number of properties. A remote authenticated attacker could use this flaw to cause memory consumption, leading to a denial of service. (CVE-2013-1845)

Ben Reser discovered that the Subversion mod_dav_svn module for Apache did not properly handle certain LOCKs. A remote authenticated attacker could use this flaw to cause Subversion to crash, leading to a denial of service. (CVE-2013-1846)

Philip Martin and Ben Reser discovered that the Subversion mod_dav_svn module for Apache did not properly handle certain LOCKs. A remote attacker could use this flaw to cause Subversion to crash, leading to a denial of service. (CVE-2013-1847)

It was discovered that the Subversion mod_dav_svn module for Apache did not properly handle certain PROPFIND requests. A remote attacker could use this flaw to cause Subversion to crash, leading to a denial of service. (CVE-2013-1849)

Greg McMullin, Stefan Fuhrmann, Philip Martin, and Ben Reser discovered that the Subversion mod_dav_svn module for Apache did not properly handle certain log REPORT requests. A remote attacker could use this flaw to cause Subversion to crash, leading to a denial of service. This issue only affected Ubuntu 12.10 and Ubuntu 13.04.
(CVE-2013-1884)

Stefan Sperling discovered that Subversion incorrectly handled newline characters in filenames. A remote authenticated attacker could use this flaw to corrupt FSFS repositories. (CVE-2013-1968)

Boris Lytochkin discovered that Subversion incorrectly handled TCP connections that were closed early. A remote attacker could use this flaw to cause Subversion to crash, leading to a denial of service.
(CVE-2013-2112).

Subversion team reports :

Subversion's svnserve server process may exit when an incoming TCP connection is closed early in the connection process.

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.

The installed version of Apache Subversion Server is prior to 1.6.23 or 1.7.x prior to 1.7.10. It is, therefore, affected by multiple remote denial of service vulnerabilities :

  - A flaw exists when handling specially crafted filenames     that could result in corruption of the FSFS repository.
    A workaround exists to install a pre-commit hook that     will prevent unsanitized filenames from being committed     into the repository. (CVE-2013-1968)

  - A flaw exists in svnserve server where improperly     handled aborted connection message are handled as     critical errors. (CVE-2013-2112)

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-0255 advisory.

    [1.6.11-10]
    - add security fixes for CVE-2013-1968, CVE-2013-2112, CVE-2014-0032

Tenable has extracted the preceding description block directly from the Oracle 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.

Updated subversion packages that fix three 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 flaw was found in the way the mod_dav_svn module handled OPTIONS requests. A remote attacker with read access to an SVN repository served via HTTP could use this flaw to cause the httpd process that handled such a request to crash. (CVE-2014-0032)

A flaw was found in the way Subversion handled file names with newline characters when the FSFS repository format was used. An attacker with commit access to an SVN repository could corrupt a revision by committing a specially crafted file. (CVE-2013-1968)

A flaw was found in the way the svnserve tool of Subversion handled remote client network connections. An attacker with read access to an SVN repository served via svnserve could use this flaw to cause the svnserve daemon to exit, leading to a denial of service.
(CVE-2013-2112)

All subversion users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, for the update to take effect, you must restart the httpd daemon, if you are using mod_dav_svn, and the svnserve daemon, if you are serving Subversion repositories via the svn:// protocol.

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2014-230:01 advisory.

    Subversion 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.
    Subversion only stores the differences between versions, instead of every complete file. Subversion is     intended to be a compelling replacement for CVS.
    Security issues fixed with this release:
     CVE-2013-1968     Subversion before 1.6.23 and 1.7.x before 1.7.10 allows remote authenticated users to cause a denial of     service (FSFS repository corruption) via a newline character in a file name.
     CVE-2013-2112     The svnserve server in Subversion before 1.6.23 and 1.7.x before 1.7.10 allows remote attackers to cause a     denial of service (exit) by aborting a connection.
     CVE-2014-0032     The get_resource function in repos.c in the mod_dav_svn module in Apache Subversion before 1.7.15 and     1.8.x before 1.8.6, when SVNListParentPath is enabled, allows remote attackers to cause a denial of     service (crash) via vectors related to the server root and request methods other than GET, as demonstrated     by the svn ls http://svn.example.com command.
