SynopsisThe remote host is missing a vendor-supplied security patch
DescriptionThe remote host is missing the patch for the advisory SUSE-SA:2003:0007 (cvs).
CVS (Concurrent Versions System) is a version control system which helps to manage concurrent editing of files by various authors.
Stefan Esser of e-matters reported a 'double free' bug in CVS server code for handling directory requests. This free() call allows an attacker with CVS read access to compromise a CVS server.
Additionally two features ('Update-prog' and 'Checkin-prog') were disabled to stop clients with write access to execute arbitrary code on the server. These features may be configurable at run-time in future releases of CVS server.
There is no temporary fix known other then disable public access to the CVS server. You do not need to update the cvs package as long as you need 'Update-prog' and 'Checkin-prog' feature and work in a trusted environment.
Otherwise install the new packages from our FTP servers please.
Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command 'rpm -Fhv file.rpm' to apply the update.
