A vulnerability was discovered in SPICE before 0.13.90 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.

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).

The RHV-M Virtual Appliance automates the process of installing and configuring the Red Hat Virtualization Manager. The appliance is available to download as an OVA file from the Customer Portal.

The following packages have been upgraded to a later upstream version:
rhevm-appliance (20170307.0). (BZ#1419968)

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)

(CVE-2016-9578)

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

Bug Fix(es) :

* Previously the name of the 'rhevm-appliance' RPM contained only a timestamp, without versioning information. In this release, the Red Hat Virtualization release will now be included in the name of the 'rhevm-appliance' RPM and will be visible from the node channel. (BZ# 1416011)

An update for imgbased, redhat-release-virtualization-host, and redhat-virtualization-host is now available for RHEV 4.X, RHEV-H, and Agents for RHEL-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 redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor.
Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks.

The following packages have been upgraded to a later upstream version:
redhat-release-virtualization-host (4.0), imgbased (0.8.16), redhat-virtualization-host (4.0). (BZ#1410848, BZ#1430244)

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).

Bug Fix(es) :

* Previously, imgbased blindly copied /etc from old layers into new layers in order to keep configuration changes between upgrades. This meant that imgbased's behavior differed from RPM, in that unmodified configuration files would be preserved across imgbased upgrades whereas 'yum upgrade' of the same packages would have replaced them.
Now, imgbased compares the sums of files to the originals kept per-layer in /usr/share/factory/etc so that unmodified configuration files are now handled appropriately. (BZ#1418179)

* Previously, some earlier versions of Red Hat Virtualization Host (RHVH) repeatedly prompted for upgrades, even when the most recent version was already installed. This was caused by the RHVH image containing a placeholder package that was made obsolete in order to upgrade. However, the package that was used to upgrade was not propagated to the rpmdb on the new image. Now, upgrading includes the update package in the rpmdb on the new image. (BZ#1422476)

* With this update, Red Hat Virtualization Host (RHVH) now includes the 'screen' package. Previously, ovirt-hosted-engine-setup invoked from a CLI warned users that the 'screen' package was not installed.
Though this was not an explicit requirement when using cockpit, including it provides a better experience if using the CLI.
(BZ#1403729)

Frediano Ziglio discovered that Spice incorrectly handled certain client messages. A remote attacker could use this issue to cause Spice to crash, resulting in a denial of service, or possibly execute arbitrary code.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several vulnerabilities were discovered in spice, a SPICE protocol client and server library. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2016-9577     Frediano Ziglio of Red Hat discovered a buffer overflow     vulnerability in the main_channel_alloc_msg_rcv_buf     function. An authenticated attacker can take advantage     of this flaw to cause a denial of service (spice server     crash), or possibly, execute arbitrary code.

  - CVE-2016-9578     Frediano Ziglio of Red Hat discovered that spice does     not properly validate incoming messages. An attacker     able to connect to the spice server could send crafted     messages which would cause the process to crash.
