Detailsinfo

A vulnerability, which was classified as critical, has been found in Sophos Endpoint Security and Control 9.0.5. Affected by this issue is an unknown functionality of the component Malware Detection. The manipulation of the argument Product with an unknown input leads to a race condition vulnerability. Using CWE to declare the problem leads to CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. Impacted is confidentiality, integrity, and availability. CVE summarizes:

** DISPUTED ** Race condition in Sophos Endpoint Security and Control 9.0.5 on Windows XP 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, via certain user-space memory changes during hook-handler execution, aka an argument-switch attack or a KHOBE attack. NOTE: the vendor disputes this issue because it is a flaw in a protection mechanism for situations where a crafted program has already begun to execute.
