> DESCRIPTION:
> Secunia Research has discovered two vulnerabilities and a weakness in
> Panda ActiveScan, which can be exploited by malicious people to
> disclose system information, cause a DoS (Denial of Service), and
> compromise a user's system.
> 
> 1) The "Reinicializar()" method in the "ActiveScan.1" ActiveX control
> allows rebooting the system when invoked. This can be exploited by
> e.g. a malicious website to reboot a user's system without any user
> confirmation.
> 
> 2) The "ObtenerTamano()" method in the "PAVPZ.SOS.1" ActiveX control
> returns the file size of a given local filename. This can be
> exploited by e.g. a malicious website to determine the presence of
> local files and the corresponding file sizes.
> 
> 3) The "Analizar()" method in the "ActiveScan.1" ActiveX control is
> not thread safe. This can be exploited by e.g. a malicious website
> via a race condition to corrupt memory and execute arbitrary code.
> 
> The vulnerabilities are confirmed in version 5.53.00. Other versions
> may also be affected.
> 
> SOLUTION:
> Update to version 5.54.01.
