1.212.1. RHSA-2009:1203: Important security update
Important
This update has already been released (prior to the GA of this release) as the security errata RHSA-2009:1203
This update has been rated as having important security impact by the Red Hat Security Response Team.
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.
Matt Lewis, of Google, reported multiple heap overflow flaws in Subversion (server and client) when parsing binary deltas. A malicious user with commit access to a server could use these flaws to cause a heap overflow on that server. A malicious server could use these flaws to cause a heap overflow on a client when it attempts to checkout or update. These heap overflows can result in a crash or, possibly, arbitrary code execution. (CVE-2009-2411)
All Subversion users should upgrade to these updated packages, which contain a backported patch to correct these issues. After installing the updated packages, the Subversion server must be restarted for the update to take effect: restart httpd if you are using mod_dav_svn, or restart svnserve if it is used.
