Description Preview
The vulnerability in AVG Internet Security 9.0.791 on Windows XP allows local users to exploit a race condition to bypass kernel-mode hook handlers. This enables them to execute malicious code that would typically be blocked by a handler but not detected by signature-based malware detection. This attack vector is known as an argument-switch attack or a KHOBE attack. It is important to note that there is some dispute regarding this issue, as it involves a flaw in a protection mechanism designed for scenarios where a crafted program has already started executing.
Overview
This CVE describes a race condition in AVG Internet Security 9.0.791 on Windows XP that can be exploited by local users to bypass kernel-mode hook handlers and execute dangerous code that evades signature-based malware detection. The vulnerability allows for an argument-switch attack or a KHOBE attack, potentially leading to unauthorized code execution.
Remediation
To mitigate this vulnerability, users are advised to update AVG Internet Security to a patched version that addresses the race condition issue. Additionally, users should follow best security practices, such as avoiding running untrusted programs and maintaining updated security software.
