VERIFY ADVISORY:
http://secunia.com/advisories/19670/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Amaya 9.x
http://secunia.com/product/9356/

DESCRIPTION:
Thomas Waldegger has discovered two vulnerabilities in Amaya, which
can be exploited by malicious people to compromise a user's system.

The vulnerabilities are caused due to boundary errors within the
parsing of various attribute values. This can be exploited to cause
stack-based buffer overflows when a user opens a specially crafted
HTML document containing certain tags with overly long attribute
values.

Successful exploitation allows execution of arbitrary code.

The vulnerabilities have been confirmed in version 9.4. Prior
versions may also be affected.

SOLUTION:
Update to version 9.5.
