CVE-2020-14355

Status Candidate

Overview

Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1. Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution.

Red Hat Security Advisory 2020-4184-01 - The Simple Protocol for Independent Computing Environments is a remote display system built for virtual environments which allows the user to view a computing 'desktop' environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures. The spice-gtk packages provide a GIMP Toolkit widget for Simple Protocol for Independent Computing Environments clients. Both Virtual Machine Manager and Virtual Machine Viewer can make use of this widget to access virtual machines using the SPICE protocol. Issues addressed include a buffer overflow vulnerability.
