Sophos SafeGuard Enterprise, SafeGuard Easy, and SafeGuard LAN Crypt are vulnerable to Local Privilege Escalation via IOCTL 0x802022E0. By crafting an input buffer we can control the execution path to the point where the constant 0x12 will be written to a user-controlled address. We can take advantage of this condition to modify the SEP_TOKEN_PRIVILEGES structure of the Token object belonging to the exploit process and grant SE_DEBUG_NAME privilege. This allows the exploit process to interact with higher privileged processes running as SYSTEM and execute code in their security context.
The specific flaw exists within the crUnpackTexGendv method. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this vulnerability to crash the VirtualBox process used for open the target.
Kernel drivers in Beckhoff TwinCAT 3.1 Build 4022.4, TwinCAT 2.11 R3 2259, and TwinCAT 3.1 lack proper validation of user-supplied pointer values. An attacker who is able to execute code on the target may be able to exploit this vulnerability to obtain SYSTEM privileges.
An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.



To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.



The update addresses this vulnerability by correcting how Win32k handles objects in memory.
An issue was discovered in MalwareFox AntiMalware. Improper access control in zam32.sys and zam64.sys allows a non-privileged process to register itself with the driver by sending IOCTL 0x80002010 and then using IOCTL 0x8000204C to \\.\ZemanaAntiMalware to elevate privileges.
