Summary: Updated rhevm-spice-client packages that fix multiple security issues are now available for Red Hat Enterprise Virtualization Manager 3. The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEV-M 3.3 - noarch 3. Description: Red Hat Enterprise Virtualization Manager provides access to virtual machines using SPICE. These SPICE client packages provide the SPICE client and usbclerk service for both Windows 32-bit operating systems and Windows 64-bit operating systems. The rhevm-spice-client package includes the mingw-virt-viewer Windows SPICE client. OpenSSL, a general purpose cryptography library with a TLS implementation, is bundled with mingw-virt-viewer. The mingw-virt-viewer package has been updated to correct the following issues: An information disclosure flaw was found in the way OpenSSL handled TLS and DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server could send a specially crafted TLS or DTLS Heartbeat packet to disclose a limited portion of memory per request from a connected client or server. Note that the disclosed portions of memory could potentially include sensitive information such as private keys. (CVE-2014-0160) It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. (CVE-2013-0169) A NULL pointer dereference flaw was found in the way OpenSSL handled TLS/SSL protocol handshake packets. A specially crafted handshake packet could cause a TLS/SSL client using OpenSSL to crash. (CVE-2013-4353) It was discovered that the TLS/SSL protocol could leak information about plain text when optional compression was used. An attacker able to control part of the plain text sent over an encrypted TLS/SSL connection could possibly use this flaw to recover other portions of the plain text. (CVE-2012-4929) Red Hat would like to thank the OpenSSL project for reporting CVE-2014-0160. Upstream acknowledges Neel Mehta of Google Security as the original reporter. The updated mingw-virt-viewer Windows SPICE client further includes OpenSSL security fixes that have no security impact on mingw-virt-viewer itself. The security fixes included in this update address the following CVE numbers: CVE-2013-6449, CVE-2013-6450, CVE-2012-2686, and CVE-2013-0166 All Red Hat Enterprise Virtualization Manager users are advised to upgrade to these updated packages, which address these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network.
