CVE-2015-2361
HighSummary
Hyper-V in Microsoft Windows 8.1 and Windows Server 2012 R2 does not properly initialize guest OS system data structures, allowing guest OS users to execute arbitrary code on the host OS or cause a denial of service (buffer overflow) by leveraging guest OS privileges.
Risk Assessment
This vulnerability may lead to the execution of malicious code on the host, posing a serious threat to the security of the entire infrastructure. Additionally, it may result in denial of service, affecting system availability.
Recommendation
It is recommended to update systems to the latest versions that include security patches. Monitoring and restricting guest OS user privileges should also be implemented.
