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

1) Certain unspecified input 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.

NOTE: This vulnerability is reportedly being actively exploited in
targeted attacks.

2) An error within the ActionScript Virtual Machine 2 (AVM2) when
handling a certain function parameters can be exploited to cause a
stack-based buffer overflow.

3) An error within the ActionScript Virtual Machine (AVM) can be
exploited to cause a stack-based buffer overflow.

4) A logic error can be exploited to corrupt memory.

5) An unspecified error can be exploited to bypass the security
control and e.g. disclose certain sensitive information.

6) A logic error when streaming certain media can be exploited to
corrupt memory.

The vulnerabilities are reported in the following products:
* Adobe Flash Player versions 10.3.183.7 and prior for Windows,
Macintosh, Linux, and Solaris.
* Adobe Flash Player versions 10.3.186.6 and prior for Android.
