[RHSA-2016:1205-01] Important: spice security update
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: spice security update Advisory ID: RHSA-2016:1205-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2016:1205 Issue date: 2016-06-06 CVE Names: CVE-2016-0749 CVE-2016-2150 ===================================================================== 1. Summary: 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: 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 memory allocation flaw, leading to a heap-based buffer overflow, was found in spice's smartcard interaction, which runs under the QEMU-KVM context on the host. A user connecting to a guest VM using spice could potentially use this flaw to crash the QEMU-KVM process or execute arbitrary code with the privileges of the host's QEMU-KVM process. (CVE-2016-0749) * A memory access flaw was found in the way spice handled certain guests using crafted primary surface parameters. A user in a guest could use this flaw to read from and write to arbitrary memory locations on the host. (CVE-2016-2150) The CVE-2016-0749 issue was discovered by Jing Zhao (Red Hat) and the CVE-2016-2150 issue was discovered by Frediano Ziglio (Red Hat). 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Applications acting as a SPICE server must be restarted for this update to take effect. Note that QEMU-KVM guests providing SPICE console access must be restarted for this update to take effect. 5. Bugs fixed (https://bugzilla.redhat.com/): 1300646 - CVE-2016-0749 spice: heap-based memory corruption within smartcard handling 1313496 - CVE-2016-2150 spice: Host memory access from guest with invalid primary surface parameters 6.
