--- Begin Message ---Package: dist Severity: grave Hi, maintainer! This message about the error concerns a few packages at once. I've tested all the packages (for Lenny) on my Debian mirror. All scripts of packages (marked as executable) were tested. In some packages I've discovered scripts with errors which may be used by a user for damaging important system files or user's files. For example if a script uses in its work a temp file which is created in /tmp directory, then every user can create symlink with the same name in this directory in order to destroy or rewrite some system or user file. Symlink attack may also lead not only to the data desctruction but to denial of service as well. Even if you create files or directories with help of function 'RANDOM' or pid(), then your system is not protected. Attacker can create many symlinks in order to destroy your data or create 'denial of service' for your package scripts. Even if you make rm(dir) for files/directories, then your system is not protected. Attacker can permanently create symlinks. This list is created with the help of script. This list is sorted by hand. Howewer in some cases mistake is possible. Please, Be understanding to possible mistakes. :) I set Severity into grave for this bug. The table of discovered problems is below.

Closes: 496412 Changes: dist (1:3.5-17-2) unstable; urgency=high . * If a script uses a temp file which is created in /tmp, then an attacker can create symlink with the same name in this directory in order to destroy or rewrite some system or user files. Symlink attack may also lead not only to the data desctruction but to denial of service as well. Creating files with rand or pid to randomize the file names is not adequate to protect the system.
