DESCRIPTION:
Some vulnerabilities have been reported in Adobe Flash Player, where
one vulnerability has an unknown impact and others can be exploited
by malicious, local users to gain escalated privileges and by
malicious people to bypass certain security restrictions, conduct
cross-site scripting and HTTP request splitting attacks, disclose
sensitive information, cause a Denial of Service (DoS), or to
potentially compromise a user's system.

1) An error when parsing specially crafted regular expressions can be
exploited to cause a heap-based buffer overflow.

For more information see vulnerability #7 in:
SA27543

2) An unspecified error in the parsing of SWF files can potentially
be exploited to execute arbitrary code.

3) An error exists when pinning a hostname to an IP address. This can
be exploited to conduct DNS rebinding attacks via allow-access-from
elements in cross-domain-policy XML documents.

4) 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.

5) Input passed to unspecified parameters when handling 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.

The vulnerability does not affect Flash Player 7.

6) Input passed to unspecified parameters when calling the
"navigateToURL" function 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.

The vulnerability only affects the Flash Player ActiveX Control for
Internet Explorer.

7) An unspecified error can be exploited to modify HTTP headers and
conduct HTTP request splitting attacks.

An error within the implementation of the Socket or XMLSocket
ActionScript classes can be exploited to determine if a port on a
remote host is opened or closed.

9) An error within the setting of memory permissions in Adobe Flash
Player for Linux can be exploited by malicious, local users to gain
escalated privileges.

10) An unspecified error exists in Adobe Flash Player and Opera on
Mac OS X.

For more information see vulnerability #3 in:
SA27277
