Description Lubomir Kundrak 2007-04-30 10:26:37 EDT

+++ 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
        Affects: FC5
        Affects: RHEL4
        Affects: RHEL5
