TITLE:
SiSoftware Sandra "sandra.sys" IOCTL Handling Vulnerabilities

SECUNIA ADVISORY ID:
SA38212

VERIFY ADVISORY:
http://secunia.com/advisories/38212/

DESCRIPTION:
Some vulnerabilities have been reported in SiSoftware Sandra, which
can be exploited by malicious, local users to cause a DoS (Denial of
Service) or gain escalated privileges.

The vulnerabilities are caused due to an errors in the sandra.sys
kernel driver when processing IOCTLs. This can be exploited to
corrupt kernel memory and execute arbitrary code in kernel space via
a specially crafted IOCTL.

Successful exploitation requires that the driver has been loaded
(e.g. by launching the application).

The vulnerabilities are reported in version 16.10.2010.1. Other
versions may also be affected.

SOLUTION:
Grant only trusted users access to affected systems.

Reportedly, some of the vulnerabilities have been fixed.
