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
Correction to comment #0:
This issue did not affect dovecot packages as shipped in Red Hat Enterprise
Linux 4, as they do not include zlib plugin. Only dovecot in Red Hat Enterprise
Linux 5 was affected.
