Please update the packages in your installation as soon as possible. _____________________________________________________________________________________________ 1. Problem Summary(From the MandrakeSoft Security Advisory) There are problems in the gnuserv application. It is possible to overrun the magic cookie buffer, and prefixes of valid magic cookies are accepted (i.e. "12" can be used if the cookie is "12345678"). 2. Impact(Also from the MandrakeSoft Security Advisory) It is possible for an attacker to execute arbitrary code. 3. Solution Update the packages from our ftp server by using the following procedure: First, uninstall the previous versions of the xemacs packages by performing the following commands in the given order: rpm -e xemacs-sumo-el rpm -e xemacs-sumo rpm -e xemacs-extra rpm -e xemacs-el rpm -e xemacs Then, install the updated versions of xemacs using the following command: rpm -Uvh ftp_path_to_filename Where ftp_path_to_filename is the following: ftp://ftp.turbolinux.com/pub/updates/6.0/security/xemacs-21.1.14-1.i386.rpm ftp://ftp.turbolinux.com/pub/updates/6.0/security/xemacs-sumo-20001023-1.noarch.rpm ftp://ftp.turbolinux.com/pub/updates/6.0/security/xemacs-sumo-el-20001023-1.noarch.rpm ftp://ftp.turbolinux.com/pub/updates/6.0/security/xemacs-el-21.1.14-1.i386.rpm Finally, upgrade the xemacs-extra package using: rpm -Uvh --force ftp_path_to_filename Where ftp_path_to_filename is the following: ftp://ftp.turbolinux.com/pub/updates/6.0/security/xemacs-extra-21.1.14-1.i386.rpm The source RPMs can be downloaded here: ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/xemacs-21.1.14-1.src.rpm ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/xemacs-sumo-20001023-1.src.rpm **Note: You must rebuild and install the RPM if you choose to download and install the SRPM. Simply installing the SRPM alone WILL NOT CLOSE THE SECURITY HOLE.
