Bash functions and the CDPATH variable are still passed through to the program running as privileged user, leaving possibilities to overload system routines. These vulnerabilities can only be exploited by users who have been granted limited super user privileges. For the stable distribution (woody) these problems have been fixed in version 1.6.6-1.2. For the unstable distribution (sid) these problems have been fixed in version 1.6.8p3. We recommend that you upgrade your sudo 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.
