Description Lubomir Kundrak 2007-04-30 14:25:26 UTC

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
        Affects: FC5
        Affects: RHEL4
        Affects: RHEL5

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.
