Mac OS X Server v10.6 through v10.6.3
Impact:  A man-in-the-middle attacker may be able to impersonate a
network account server
Description:  When binding to a network account server via System
Preferences, Open Directory will automatically negotiate an
unprotected connection to the server if it is not possible to connect
to the server with Secure Sockets Layer (SSL). A man-in-the-middle
attacker may be able to impersonate the network account server, which
may lead to arbitrary code execution with system privileges. This
issue is addressed by providing an option to require a secure
connection. This issue does not affect systems prior to Mac OS X
v10.6.

Impact:  A remote attacker may gain access to accounts served by Ruby
WEBrick
Description:  A cross-site scripting issue exists in the Ruby WEBrick
HTTP server's handling of error pages. Accessing a maliciously
crafted URL in certain web browsers may cause the error page to be
treated as UTF-7, allowing JavaScript injection. The issue is
addressed by setting UTF-8 as the default character set in HTTP error
responses. Credit: Apple.

SMB File Server
CVE-ID:  CVE-2010-1381

Mac OS X v10.6 through v10.6.3, Mac OS X Server v10.6 through v10.6.3
Impact:  Viewing maliciously crafted Wiki content may result in a
cross-site scripting attack
Description:  The Wiki Server does not specify an explicit character
set when serving HTML documents in response to user requests. An
attacker with the ability to post or comment on Wiki Server hosted
content may include scripts encoded in an alternate character set.
This may lead to a cross-site scripting attack against users of the
Wiki Server. The issue is addressed by specifying a character set for
the document in HTTP responses.
