Package: newsgate
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.

Version: 1.6-23+rm

The newsgate package has been removed from Debian testing, unstable and
experimental, so I am now closing the bugs that were still opened
against it.

For more information about this package's removal, read
http://bugs.debian.org/496783 . That bug might give the reasons why
this package was removed, and suggestions of possible replacements.

Don't hesitate to reply to this mail if you have any question.

Thank you for your contribution to Debian.
