4) Description of Vulnerability

Secunia Research has discovered some vulnerabilities in various Panda 
products, which can be exploited by malicious, local users to cause a 
DoS (Denial of Service).

The vulnerabilities are caused by array-indexing errors in the 
APPFLT.SYS driver when parsing input data for certain IOCTLs (e.g. 
6660C8Ch, 6660C94h, 6660C98h, 6660CB0h, 6660CB4h, and 6660CB8h). This 
can be exploited to trigger an access violation when attempting to 
read data from an invalid memory address.

Successful exploitation causes the system to restart.

====================================================================== 
5) Solution 

Apply hotfixes available from Panda Security.
