DESCRIPTION:
Multiple vulnerabilities have been reported in Microsoft SharePoint,
which can be exploited by malicious users to bypass certain security
restrictions and by malicious people to conduct cross-site scripting
and spoofing attacks.

1) Certain input is not properly sanitised in the "SafeHTML" API
before being returned to the user.

For more information see vulnerability #2:
SA49412

2) Certain unspecified input is not properly sanitised in
scriptresx.ashx before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

3) An error when validating search scope permissions can be exploited
to view or modify another user's search scope.

4) Certain unspecified input associated with a username is not
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

5) Certain unspecified input associated with a URL is not properly
verified before being used to redirect users. This can be exploited
to redirect a user to an arbitrary website e.g. when a user clicks a
specially crafted link to the affected script hosted on a trusted
domain.

6) Certain unspecified input associated with a reflected list
parameter is not properly sanitised before being returned to the
user. This can be exploited to execute arbitrary HTML and script code
in a user's browser session in context of an affected site.

SOLUTION:
Apply patches.
