Summary
Red Hat Security Advisory: spice security update

Notes

Topic
An update for spice is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
The Simple Protocol for Independent Computing Environments (SPICE) 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. Security Fix(es): * A vulnerability was discovered in spice server's protocol handling. An authenticated attacker could send specially crafted messages to the spice server, causing out-of-bounds memory accesses, leading to parts of server memory being leaked or a crash. (CVE-2017-7506) This issue was discovered by Frediano Ziglio (Red Hat).
