It normally drops root privileges after successfully initializing itself. However, if initialization fails due to a missing configuration file, root privileges are not dropped, and xatitv executes the system(3) function to launch its configuration program without sanitizing user-supplied environment variables. By exploiting this vulnerability, a local user could gain root privileges if the configuration file does not exist. However, a default configuration file is supplied with the package, and so this vulnerability is not exploitable unless this file is removed by the administrator. For the current stable distribution (woody) this problem has been fixed in version 0.0.5-6woody1. For the unstable distribution (sid), this problem will be fixed soon. We recommend that you update your gatos package. Upgrade Instructions - - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
