Updated subversion package fixes security vulnerabilities :

mod_dontdothat allows you to block update REPORT requests against certain paths in the repository. It expects the paths in the REPORT request to be absolute URLs. Serf based clients send relative URLs instead of absolute URLs in many cases. As a result these clients are not blocked as configured by mod_dontdothat (CVE-2013-4505).

When SVNAutoversioning is enabled via SVNAutoversioning on, commits can be made by single HTTP requests such as MKCOL and PUT. If Subversion is built with assertions enabled any such requests that have non-canonical URLs, such as URLs with a trailing /, may trigger an assert. An assert will cause the Apache process to abort (CVE-2013-4558).

The is_this_legal function in mod_dontdothat for Apache Subversion 1.4.0 through 1.7.13 and 1.8.0 through 1.8.4 allows remote attackers to bypass intended access restrictions and possibly cause a denial of service (resource consumption) via a relative URL in a REPORT request.

The get_parent_resource function in repos.c in mod_dav_svn Apache HTTPD server module in Subversion 1.7.11 through 1.7.13 and 1.8.1 through 1.8.4, when built with assertions enabled and SVNAutoversioning is enabled, allows remote attackers to cause a denial of service (assertion failure and Apache process abort) via a non-canonical URL in a request, as demonstrated using a trailing /.

This update includes the latest stable release of Apache Subversion 1.7, version 1.7.14. Two security fixes are included :

New subversion packages are available for Slackware 14.0, 14.1, and
-current to fix denial-of-service issues.

The remote Solaris system is missing necessary patches to address security updates :

  - The mod_dav_svn Apache HTTPD server module in Subversion     1.6.x through 1.6.20 and 1.7.0 through 1.7.8 allows     remote attackers to cause a denial of service (NULL     pointer dereference and crash) via a PROPFIND request     for an activity URL. (CVE-2013-1849)

  - The is_this_legal function in mod_dontdothat for Apache     Subversion 1.4.0 through 1.7.13 and 1.8.0 through 1.8.4     allows remote attackers to bypass intended access     restrictions and possibly cause a denial of service     (resource consumption) via a relative URL in a REPORT     request. (CVE-2013-4505)

Subversion Project reports :

mod_dontdothat does not restrict requests from serf based clients

mod_dontdothat allows you to block update REPORT requests against certain paths in the repository. It expects the paths in the REPORT request to be absolute URLs. Serf based clients send relative URLs instead of absolute URLs in many cases. As a result these clients are not blocked as configured by mod_dontdothat.

mod_dav_svn assertion triggered by non-canonical URLs in autoversioning commits

When SVNAutoversioning is enabled via SVNAutoversioning on commits can be made by single HTTP requests such as MKCOL and PUT. If Subversion is built with assertions enabled any such requests that have non-canonical URLs, such as URLs with a trailing /, may trigger an assert. An assert will cause the Apache process to abort.

This update fixes the following issues with subversion (CVE-2013-4505,CVE-2013-4558) :

  - bnc#850747: update to 1.8.5

  - CVE-2013-4505: mod_dontdothat does not restrict requests     from serf clients.

  - CVE-2013-4558: mod_dav_svn assertion triggered by     autoversioning commits.

  + Client-side bugfixes :

  - fix externals that point at redirected locations

  - diff: fix assertion with move inside a copy

  + Server-side bugfixes :

  - mod_dav_svn: Prevent crashes with some 3rd party modules

  - mod_dav_svn: canonicalize paths properly

  - mod_authz_svn: fix crash of mod_authz_svn with invalid     config

  - hotcopy: fix hotcopy losing revprop files in packed     repos

  + Other tool improvements and bugfixes :

  - mod_dontdothat: Fix the uri parser

  + Developer-visible changes :

  - fix compilation with '--enable-optimize' with clang

  - add test to fail when built against broken ZLib

  + Bindings :

  - ctypes-python: build with compiler selected via     configure

  - require python-sqlite when running regression tests for     all targets, no longer pulled in implicitly

  - print error logs on regression test failures

  - fix regression tests for ppc/ppc64 architectures, found     in openSUSE package build and fixed with upstream     developers

  - if running regression tests, also run them against bdb     backend

  - update keyring, use Subversion Project Management     Committee keyring rather than all committers

The installed version of Subversion Server is affected by multiple denial of service vulnerabilities :

  - An error exists related to the 'mod_dontdothat' module     and handling relative URLs sent from serf-based     clients. (CVE-2013-4505)

  - An error exists related to the 'mod_dav_svn' module and     handling unspecified requests. Note that this issue     reportedly only affects the 1.7 and 1.8 branches,     including versions 1.7.11 through 1.7.13 and 1.8.1     through 1.8.4. (CVE-2013-4558)
