CVS is useful for everyone from individual developers to large, distributed teams: * Its client-server access method lets developers access the latest code from anywhere there's an Internet connection. * Its unreserved check-out model to version control avoids artificial conflicts common with the exclusive check-out model. * Its client tools are available on most platforms. - - -> Problem description: - - ------------------------ SERVER SECURITY ISSUES * Piped checkouts of paths above $CVSROOT no longer work. Previously, clients could have requested the contents of RCS archive files anywhere on a CVS server. CLIENT SECURITY ISSUES * Clients now check paths from the server to verify that they are within one of the sandboxes the user requested be updated. Previously, a trojan server could have written or overwritten files anywhere the user had access, presenting a serious security risk. - - -> Action: - - ------------------------   We recommend that all systems with this package installed be upgraded.   Please note that if you do not need the functionality provided by this   package, you may want to remove it from your system. - - -> Location: - - ---------------------   You can download the latest version of this package in NEPOTE format from:   - - -> Nepote Update: - - --------------------- See this instructions to update the port of this package:         # wget http://www.netwosix.org/0011/nepote         # sh nepote (to install the new and updated package) - - -> References - - ---------------------         Specific references for this advisory:              http://ccvs.cvshome.org/source/browse/ccvs/NEWS?rev=1.116.2.92&content-type=text/x-cvsweb-markup - - -> About Linux Netwosix: - - --------------------------------- Linux Netwosix is a powerful and optimized Linux distribution for servers and Network Security related jobs.  It can also be used for special operations such as penetration testing with its big collection of security oriented software and sources.
