TITLE:
Adobe Flash Player Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA28083

VERIFY ADVISORY:
http://secunia.com/advisories/28083/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Cross Site Scripting, System access

WHERE:
>From remote

REVISION:
1.1 originally posted 2008-04-09

SOFTWARE:
Adobe Flash Player 9.x
http://secunia.com/product/11901/

DESCRIPTION:
Some vulnerabilities have been reported in Adobe Flash Player, which
can be exploited by malicious people to bypass certain security
restrictions, conduct cross-site scripting attacks, or to potentially
compromise a user's system.

1) A boundary error exists in the processing of "Declare Function
(V7)" tags. This can be exploited to cause a heap-based buffer
overflow via specially crafted flags.

2) An integer overflow in the processing of multimedia files can be
exploited to cause a buffer overflow.   

Successful exploitation of the vulnerabilities may allow execution of
arbitrary code.

3) Errors when pinning a hostname to an IP address can be exploited
to conduct DNS rebinding attacks. 

This is related to vulnerability #3 in:
SA28161

4) An error when sending HTTP headers can be exploited to bypass
cross-domain policy files.

5) An error exists in the enforcing of cross-domain policy files.
This can be exploited to bypass certain security restrictions on web
servers hosting cross-domain policy files.

This is related to vulnerability #4 in:
SA28161

6) Input passed to unspecified parameters when handling e.g. the
"asfunction:" protocol is not properly sanitised before being
returned to the user. This can be exploited to inject arbitrary HTML
and script code in a user's browser session in context of an affected
site.

This is related to vulnerability #5 in:
SA28161
