| Vector | AV:L/AC:H/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Avira Premium Security Suite version 10.0.0.536
Description
A race condition in the software allows local users to bypass kernel-mode hook handlers and execute dangerous code that would otherwise be blocked by a handler but not blocked by signature-based malware detection. This is achieved via certain user-space memory changes during hook-handler execution, also known as an argument-switch attack or a KHOBE attack. The issue is disputed by some third parties as it is a flaw in a protection mechanism for situations where a crafted program has already begun to execute.
Recommendations
For Avira Premium Security Suite version 10.0.0.536, consider disabling the kernel-mode hook handlers as a temporary workaround until a patch is available. Restrict access to user-space memory to minimize the risk of exploitation. Avoid using the software on Windows XP until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
