4) Description of Vulnerability

Secunia Research has discovered a vulnerability in various Panda 
products, which can be exploited by malicious, local users to gain 
escalated privileges.

The vulnerability is caused by a boundary error 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 cause a buffer overflow via specially crafted input data 
containing an overly long string.

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

Apply hotfixes available from Panda Security.
