-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: spice-server security update Advisory ID: RHSA-2017:0253-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2017-0253.html Issue date: 2017-02-06 CVE Names: CVE-2016-9577 CVE-2016-9578 ===================================================================== 1. Summary: An update for spice-server is now available for Red Hat Enterprise Linux 6. 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - x86_64 Red Hat Enterprise Linux Workstation (v. 6) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - x86_64 3. Description: The Simple Protocol for Independent Computing Environments (SPICE) is a remote display protocol for virtual environments. SPICE users can access a virtualized desktop or server from the local system or any system with network access to the server. SPICE is used in Red Hat Enterprise Linux for viewing virtualized guests running on the Kernel-based Virtual Machine (KVM) hypervisor or on Red Hat Enterprise Virtualization Hypervisors. 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). 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 All applications using SPICE (most notably all QEMU-KVM instances using the SPICE console) must be restarted for this update to take effect. 5. Bugs fixed (https://bugzilla.redhat.com/): 1399566 - CVE-2016-9578 spice: Remote DoS via crafted message 1401603 - CVE-2016-9577 spice: Buffer overflow in main_channel_alloc_msg_rcv_buf when reading large messages 6.
