Fedora Update Notification
FEDORA-2011-8352
2011-06-15 17:46:08
--------------------------------------------------------------------------------

Name        : subversion
Product     : Fedora 15
Version     : 1.6.17
Release     : 1.fc15
URL         : http://subversion.apache.org/
Summary     : A Modern Concurrent Version Control System
Description :
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.

--------------------------------------------------------------------------------
Update Information:

This update includes the latest release of Subversion, fixing three security issues:

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)

The Fedora Project 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.

The following bugs are also fixed in this release:

* make 'blame -g' more efficient on with large mergeinfo
* preserve log message with a non-zero editor exit
* fix FSFS cache performance on 64-bit platforms
* make svn cleanup tolerate obstructed directories
* fix deadlock in multithreaded servers serving FSFS repositories
* detect very occasional corruption and abort commit
* fixed: file externals cause non-inheritable mergeinfo
* fixed: file externals cause mixed-revision working copies
* fixed: write-through proxy could direcly commit to slave
* detect a particular corruption condition in FSFS
* improve error message when clients refer to unkown revisions
* bugfixes and optimizations to the DAV mirroring code
* fixed: locked and deleted file causes tree conflict
* fixed: update touches locked file with svn:keywords property
* fix svnsync handling of directory copyfrom
* fix 'log -g' excessive duplicate output
* fix svnsync copyfrom handling bug with BDB
* server-side validation of svn:mergeinfo syntax during commit
--------------------------------------------------------------------------------
