Synopsis

The remote Fedora host is missing a security update.

Description

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

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

Solution

Update the affected subversion package.
