Synopsis :

The remote Virtuozzo host is missing a security update.

Description :

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 Moderate. 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.

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 in the server's protocol
handling. An authenticated attacker could send crafted messages to the
spice server causing a heap overflow leading to a crash or possible
code execution. (CVE-2016-9577)

* A vulnerability was discovered in spice in the server's protocol
handling. An attacker able to connect to the spice server could send
crafted messages which would cause the process to crash.
(CVE-2016-9578)

These issues were discovered by Frediano Ziglio (Red Hat).

Note that Tenable Network Security has attempted to extract the
preceding description block directly from the corresponding Red Hat
security advisory. Virtuozzo provides no description for VZLSA
advisories. Tenable has attempted to automatically clean and format
it as much as possible without introducing additional issues.
