Published: Translated: NVD NIST

Summary

CVE-2017-7980 involves a heap-based buffer overflow in the Cirrus CLGD 54xx VGA Emulator in Quick Emulator (Qemu) version 2.8 and earlier. This allows local guest OS users to execute arbitrary code or cause a denial of service (crash) via vectors related to a VNC client updating its display after a VGA operation.

Risk Assessment

This vulnerability poses a risk of unauthorized code execution by local users, potentially leading to serious security incidents and system crashes. Organizations should be aware of the potential threats associated with using vulnerable versions of Qemu.

Recommendation

It is recommended to upgrade Qemu to a version newer than 2.8 to mitigate this vulnerability. Additionally, access to the guest OS should be restricted to trusted users.
