DESCRIPTION:
Two vulnerabilities have been discovered in certain Panda products,
which can be exploited by malicious, local users to potentially gain
escalated privileges.

1) Insufficient input validation in the APPFLT.SYS driver when
processing 06660D4Ch and 06660D50h IOCTLs can be exploited to cause a
buffer overflow.

2) Missing input validation in the APPFLT.SYS driver when processing
the 06660E1Ch IOCTL can be exploited to corrupt memory by copying
user-controlled data to an semi-arbitrary virtual memory address.

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

The vulnerabilities are confirmed in the following products:
* Panda Global Protection 2010 version 3.01.00 (Appflt.sys version
2.3.0.8).
* Panda Global Protection 2011 version 4.00.00 (Appflt.sys version
2.3.0.10).
* Panda Internet Security 2011 version 16.00.00 (Appflt.sys version
2.3.0.10).

SOLUTION:
Restrict access to trusted users only.
