Description Enrico Scholz 2005-04-28 00:16:14 UTC
Description of problem:

Scriptlets contain 

| %pre
| ...
| touch /tmp/dovecot-restart-after-rpm-install

As /tmp is writable by everybody, an attacker could cause the creation of
arbitrary files. It would be better to use a directory like /var/run for such
flags as it is writable by root only.


Version-Release number of selected component (if applicable):

dovecot-0.99.14-2.fc4

fixed in dovecot-0.99.14-5.fc4
