Scientific Linux Security Update : subversion on SL6.x i386/x86_64
Medium Nessus Plugin ID 60955
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionAn access restriction bypass flaw was found in the mod_dav_svn module.
If the SVNPathAuthz directive was set to 'short_circuit', certain access rules were not enforced, possibly allowing sensitive repository data to be leaked to remote users. Note that SVNPathAuthz is set to 'On' by default. (CVE-2010-3315)
A server-side memory leak was found in the Subversion server. If a malicious, remote user performed 'svn blame' or 'svn log' operations on certain repository files, it could cause the Subversion server to consume a large amount of system memory. (CVE-2010-4644)
A NULL pointer dereference flaw was found in the way the mod_dav_svn module processed certain requests. If a malicious, remote user issued a certain type of request to display a collection of Subversion repositories on a host that has the SVNListParentPath directive enabled, it could cause the httpd process serving the request to crash. Note that SVNListParentPath is not enabled by default.
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.
SolutionUpdate the affected packages.
