Integer Overflow in VGA Module of QEMU

CVE-2016-3712

Summary

The VGA module in QEMU is susceptible to an integer overflow issue, which allows local users operating within a guest OS to manipulate VGA registers in VBE mode. This manipulation can trigger an out-of-bounds read, potentially leading to a denial of service through the crash of the QEMU process. This vulnerability emphasizes the importance of securing the virtualization environment to protect against unauthorized access and system interruptions.
