APPLE-SA-2003-02-25 Mac OS X 10.2.4 Server
Mac OS X 10.2.4 Server Software Update is now available. It contains
fixes for
the following potential security issues:
* QuickTime Streaming Server: Fixes CAN-2003-0050 QTSS Arbitrary command
execution. The QuickTime Streaming Administration Server relies on the
parse_xml.cgi application to authenticate and interface with the user.
This CGI
can pass unvalidated input which could allow a remote attacker to
execute
arbitrary code on the server and to gain root privileges. Credit to
Dave G.
from @stake, Inc. for finding this vulnerability.
* QuickTime Streaming Server: Fixes CAN-2003-0051 QTSS Physical path
revelation.
The QuickTime Streaming Administration Server relies on the
parse_xml.cgi
application to authenticate and interface with the user. This CGI
could be used
to reveal the physical path upon which the Darwin/Quicktime
Administration
Servers are installed within. Credit to @stake, Inc. for finding this
vulnerability.
* QuickTime Streaming Server: Fixes CAN-2003-0052 QTSS Directory
listings. The
QuickTime Streaming Administration Server relies on the parse_xml.cgi
application to authenticate and interface with the user. This CGI
could be used
to reveal arbitrary directory listings due to the lack of user input
validation
within the application. Credit to Ollie Whitehouse from @stake, Inc.
for
finding this vulnerability.
* QuickTime Streaming Server: Fixes CAN-2003-0053 QTSS Login
credentials. The
QuickTime Streaming Administration Server relies on the parse_xml.cgi
application to authenticate and interface with the user. A
vulnerability in the
handling of error messages from this CGI could be used in a cross-site
scripting
attack to gain valid login credentials. Credit to Ollie Whitehouse
from @stake,
Inc. for finding this vulnerability.
* QuickTime Streaming Server: Fixes CAN-2003-0054 Arbitrary command
execution
when viewing QTSS logs. If an unauthenticated user of QuickTime
Streaming Server
makes a request to the streaming port, the request is then written to
the log
file. It is possible to craft the request such that arbitrary code can
be
executed when the logs are viewed by the system administrator via a
browser.

vulnerability.
* QuickTime Streaming Server: Fixes CAN-2003-0055 Buffer overflow in MP3
Broadcasting application. There is a buffer overflow in the stand-alone
MP3Broadcaster application. An MP3 file which has a filename of over
256 bytes
will cause a buffer overflow to occur. This could be used by local/ftp
users to
obtain elevated privileges. Credit to Ollie Whitehouse from @stake,
Inc. for
finding this vulnerability.
* Sendmail: Fixes CAN-2002-0906 Buffer overflow in Sendmail before
8.12.5, when
configured to use a custom DNS map to query TXT records, could permit a
denial
of service attack and possibly allow execution of arbitrary code. Mac
OS X
10.2.4 contains Sendmail 8.12.6 with the SMRSH fix applied to also
address
CAN-2002-1165 .
* AFP: Fixes CAN-2003-0049 "AFP login permissions for the system
administrator". Provides an option whereby a system administrator may
or may
not be allowed to log in as a user, authenticating via their admin
password.
Previously, administrators could always log in as a user,
authenticating via
their own admin password.
* Classic: Fixes CAN-2003-0088 , where an attacker may change an
environment
variable to create arbitrary files or overwrite existing files, which
could lead
to obtaining elevated privileges. Credit to Dave G. from @stake, Inc.
for
discovering this issue.
* Samba: Previous releases of Mac OS X are not vulnerable to
CAN-2002-1318 , an
issue in Samba's length checking for encrypted password changes. Mac
OS X
currently uses Directory Services for authentication, and does not call
the
vulnerable Samba function. However, to prevent a potential future
exploit via
this function, the patch from Samba 2.2.7 was applied although the
version of
Samba was not changed for this update release. Further information is
available
from: http://samba.org/samba/whatsnew/samba-2.2.7.html
* Integrated WebDAV Digest Authentication: The mod_digest_apple Apache
module
has been added to more easily enable digest authentication for an
existing
WebDAV realm. This eliminates the need to maintain a separate digest
file
containing the list of authorized users, passwords, and realms.
mod_digest_apple works in coordination with Open Directory for user
authentication. For further details, open the Help Viewer after
installing Mac
OS X Server version 10.2.4, select Mac OS X Server Help in the drawer,
and
search for "New: Enabling Integrated WebDAV Digest Authentication."
