Hi!
Well, yesterday out of nothing my webmailer roundcube started to refuse
to work. At least as I remember it. For some reasons reloading the Inbox
just showed the "Loading..." message on the screen, but there was no
list of mails anymore. Funny enough other folders do actually work as
before. But anyway, doing an update did not help and improve anything.
(I really don't know whether I updated before or after because of the
first occurence of this issue.)
There's an entry in syslog when loading the Inbox folder:
Oct 26 07:24:59 muaddib suhosin[32432]: ALERT - Include filename
('http://www.gnu.org/s/hello/manual/automake/ ?.php') is an URL that is
not allowed (attacker '127.0.0.1', file
'/usr/share/roundcube/program/include/iniset.php', line 110
This lead to bug #1488086 in the Roundcube issue tracker which states:
This messages made me wonder why suhosin thinks there's an include
going on. Line 111 of iniset.php shows:
include_once("$filename.php");
It seems like roundcube wants to include what is displayed in the
subject, which happens to be a url - and suhosin legitimately blocks
this attempt.
In short, I can send an email to a user on a suhosin protected mail
server and make his inbox unavailable. Needless to say, the user cannot
delete this email himself via RoundCube. In my case, I had to delete the
email file on the server to make roundcube show the inbox again.
In Debian there's bug #619411 that is related to PATH setting in
iniset.php, but I'm not sure if this is really related to #1488086 in
the Roundcube issue tracker and my problem? However, disabling suhosin
doesn't seem the right way to "solve" this issue and the trac issue
tracker suggests a security related problem.
Regards,
Ingo
