+++ This bug was initially created as a clone of Bug #238439 +++
Description of problem:
In case zlib plugin is enabled, dovecot didn't check if mbox path
contained ".." which could be exploited to read compressed mailboxes
of other users.
As the dovecot-news post referred to in URL field states, this is an
unlikely scenario, as it moreover needs the files to be readable by
UID the dovecot is running under after the malicious user logs in.
Version-Release number of selected component (if applicable):
Does not Affect: FC6
dovecot-1.0-0.beta8.4.fc5 has been pushed for fc5, which should resolve this issue. If these problems are still present in this version, then please make note of it in this bug report.
