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.

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.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has openssl packages installed that are affected by multiple vulnerabilities:

  - OpenSSL 1.0.2 (starting from version 1.0.2b) introduced     an error state mechanism. The intent was that if a     fatal error occurred during a handshake then OpenSSL     would move into the error state and would immediately     fail if you attempted to continue the handshake. This     works as designed for the explicit handshake functions     (SSL_do_handshake(), SSL_accept() and SSL_connect()),     however due to a bug it does not work correctly if     SSL_read() or SSL_write() is called directly. In that     scenario, if the handshake fails then a fatal error will     be returned in the initial function call. If     SSL_read()/SSL_write() is subsequently called by the     application for the same SSL object then it will succeed     and the data is passed without being decrypted/encrypted     directly from the SSL/TLS record layer. In order to     exploit this issue an application bug would have to be     present that resulted in a call to     SSL_read()/SSL_write() being issued after having already     received a fatal error. OpenSSL version 1.0.2b-1.0.2m     are affected. Fixed in OpenSSL 1.0.2n. OpenSSL 1.1.0 is     not affected. (CVE-2017-3737)

  - There is an overflow bug in the AVX2 Montgomery     multiplication procedure used in exponentiation with     1024-bit moduli. No EC algorithms are affected. Analysis     suggests that attacks against RSA and DSA as a result of     this defect would be very difficult to perform and are     not believed likely. Attacks against DH1024 are     considered just feasible, because most of the work     necessary to deduce information about a private key may     be performed offline. The amount of resources required     for such an attack would be significant. However, for an     attack on TLS to be meaningful, the server would have to     share the DH1024 private key among multiple clients,     which is no longer an option since CVE-2016-0701. This     only affects processors that support the AVX2 but not     ADX extensions like Intel Haswell (4th generation).
    Note: The impact from this issue is similar to     CVE-2017-3736, CVE-2017-3732 and CVE-2015-3193. OpenSSL     version 1.0.2-1.0.2m and 1.1.0-1.1.0g are affected.
    Fixed in OpenSSL 1.0.2n. Due to the low severity of this     issue we are not issuing a new release of OpenSSL 1.1.0     at this time. The fix will be included in OpenSSL 1.1.0h     when it becomes available. The fix is also available in     commit e502cc86d in the OpenSSL git repository.
    (CVE-2017-3738)

  - There is a carry propagating bug in the x86_64     Montgomery squaring procedure in OpenSSL before 1.0.2m     and 1.1.0 before 1.1.0g. No EC algorithms are affected.
    Analysis suggests that attacks against RSA and DSA as a     result of this defect would be very difficult to perform     and are not believed likely. Attacks against DH are     considered just feasible (although very difficult)     because most of the work necessary to deduce information     about a private key may be performed offline. The amount     of resources required for such an attack would be very     significant and likely only accessible to a limited     number of attackers. An attacker would additionally need     online access to an unpatched system using the target     private key in a scenario with persistent DH parameters     and a private key that is shared between multiple     clients. This only affects processors that support the     BMI1, BMI2 and ADX extensions like Intel Broadwell (5th     generation) and later or AMD Ryzen. (CVE-2017-3736)

  - OpenSSL 0.9.7 before 0.9.7l and 0.9.8 before 0.9.8d     allows remote attackers to cause a denial of service     (infinite loop and memory consumption) via malformed     ASN.1 structures that trigger an improperly handled     error condition. (CVE-2006-2937)

  - OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and     earlier versions allows attackers to cause a denial of     service (CPU consumption) via parasitic public keys with     large (1) public exponent or (2) public modulus     values in X.509 certificates that require extra time to     process when using RSA signature verification.
    (CVE-2006-2940)

  - Buffer overflow in the SSL_get_shared_ciphers function     in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and     earlier versions has unspecified impact and remote     attack vectors involving a long list of ciphers.
    (CVE-2006-3738)

  - OpenSSL before 0.9.7, 0.9.7 before 0.9.7k, and 0.9.8     before 0.9.8c, when using an RSA key with exponent 3,     removes PKCS-1 padding before generating a hash, which     allows remote attackers to forge a PKCS #1 v1.5     signature that is signed by that RSA key and prevents     OpenSSL from correctly verifying X.509 and other     certificates that use PKCS #1. (CVE-2006-4339)

  - The get_server_hello function in the SSLv2 client code     in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and     earlier versions allows remote servers to cause a denial     of service (client crash) via unknown vectors that     trigger a null pointer dereference. (CVE-2006-4343)

  - The BN_from_montgomery function in crypto/bn/bn_mont.c     in OpenSSL 0.9.8e and earlier does not properly perform     Montgomery multiplication, which might allow local users     to conduct a side-channel attack and retrieve RSA     private keys. (CVE-2007-3108)

  - Off-by-one error in the DTLS implementation in OpenSSL     0.9.8 before 0.9.8f allows remote attackers to execute     arbitrary code via unspecified vectors. (CVE-2007-4995)

  - Off-by-one error in the SSL_get_shared_ciphers function     in OpenSSL 0.9.7 up to 0.9.7l, and 0.9.8 up to 0.9.8f,     might allow remote attackers to execute arbitrary code     via a crafted packet that triggers a one-byte buffer     underflow. NOTE: this issue was introduced as a result     of a fix for CVE-2006-3738. As of 20071012, it is     unknown whether code execution is possible.
    (CVE-2007-5135)

  - Double free vulnerability in OpenSSL 0.9.8f and 0.9.8g,     when the TLS server name extensions are enabled, allows     remote attackers to cause a denial of service (crash)     via a malformed Client Hello packet. NOTE: some of these     details are obtained from third party information.
    (CVE-2008-0891)

  - OpenSSL 0.9.8f and 0.9.8g allows remote attackers to     cause a denial of service (crash) via a TLS handshake     that omits the Server Key Exchange message and uses     particular cipher suites, which triggers a NULL     pointer dereference. (CVE-2008-1672)

  - The dtls1_buffer_record function in ssl/d1_pkt.c in     OpenSSL 0.9.8k and earlier 0.9.8 versions allows remote     attackers to cause a denial of service (memory     consumption) via a large series of future epoch DTLS     records that are buffered in a queue, aka DTLS record     buffer limitation bug. (CVE-2009-1377)

  - Multiple memory leaks in the     dtls1_process_out_of_seq_message function in     ssl/d1_both.c in OpenSSL 0.9.8k and earlier 0.9.8     versions allow remote attackers to cause a denial of     service (memory consumption) via DTLS records that (1)     are duplicates or (2) have sequence numbers much greater     than current sequence numbers, aka DTLS fragment     handling memory leak. (CVE-2009-1378)

  - Use-after-free vulnerability in the     dtls1_retrieve_buffered_fragment function in     ssl/d1_both.c in OpenSSL 1.0.0 Beta 2 allows remote     attackers to cause a denial of service (openssl s_client     crash) and possibly have unspecified other impact via a     DTLS packet, as demonstrated by a packet from a server     that uses a crafted server certificate. (CVE-2009-1379)

  - The TLS protocol, and the SSL protocol 3.0 and possibly     earlier, as used in Microsoft Internet Information     Services (IIS) 7.0, mod_ssl in the Apache HTTP Server     2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5     and earlier, Mozilla Network Security Services (NSS)     3.12.4 and earlier, multiple Cisco products, and other     products, does not properly associate renegotiation     handshakes with an existing connection, which allows     man-in-the-middle attackers to insert data into HTTPS     sessions, and possibly other types of sessions protected     by TLS or SSL, by sending an unauthenticated request     that is processed retroactively by a server in a post-     renegotiation context, related to a plaintext     injection attack, aka the Project Mogul issue.
    (CVE-2009-3555)

  - Memory leak in the zlib_stateful_finish function in     crypto/comp/c_zlib.c in OpenSSL 0.9.8l and earlier and     1.0.0 Beta through Beta 4 allows remote attackers to     cause a denial of service (memory consumption) via     vectors that trigger incorrect calls to the     CRYPTO_cleanup_all_ex_data function, as demonstrated by     use of SSLv3 and PHP with the Apache HTTP Server, a     related issue to CVE-2008-1678. (CVE-2009-4355)

  - The Cryptographic Message Syntax (CMS) implementation in     crypto/cms/cms_asn1.c in OpenSSL before 0.9.8o and 1.x     before 1.0.0a does not properly handle structures that     contain OriginatorInfo, which allows context-dependent     attackers to modify invalid memory locations or conduct     double-free attacks, and possibly execute arbitrary     code, via unspecified vectors. (CVE-2010-0742)

  - RSA verification recovery in the EVP_PKEY_verify_recover     function in OpenSSL 1.x before 1.0.0a, as used by     pkeyutl and possibly other applications, returns     uninitialized memory upon failure, which might allow     context-dependent attackers to bypass intended key     requirements or obtain sensitive information via     unspecified vectors. NOTE: some of these details are     obtained from third party information. (CVE-2010-1633)

  - Multiple race conditions in ssl/t1_lib.c in OpenSSL     0.9.8f through 0.9.8o, 1.0.0, and 1.0.0a, when multi-     threading and internal caching are enabled on a TLS     server, might allow remote attackers to execute     arbitrary code via client data that triggers a heap-     based buffer overflow, related to (1) the TLS server     name extension and (2) elliptic curve cryptography.
    (CVE-2010-3864)

  - OpenSSL before 0.9.8q, and 1.0.x before 1.0.0c, when     SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled, does     not properly prevent modification of the ciphersuite in     the session cache, which allows remote attackers to     force the downgrade to an unintended cipher via vectors     involving sniffing network traffic to discover a session     identifier. (CVE-2010-4180)

  - ssl/t1_lib.c in OpenSSL 0.9.8h through 0.9.8q and 1.0.0     through 1.0.0c allows remote attackers to cause a denial     of service (crash), and possibly obtain sensitive     information in applications that use OpenSSL, via a     malformed ClientHello handshake message that triggers an     out-of-bounds memory access, aka OCSP stapling     vulnerability. (CVE-2011-0014)

  - crypto/x509/x509_vfy.c in OpenSSL 1.0.x before 1.0.0e     does not initialize certain structure members, which     makes it easier for remote attackers to bypass CRL     validation by using a nextUpdate value corresponding to     a time in the past. (CVE-2011-3207)

  - OpenSSL 0.9.8s and 1.0.0f does not properly support DTLS     applications, which allows remote attackers to cause a     denial of service (crash) via unspecified vectors     related to an out-of-bounds read. NOTE: this     vulnerability exists because of an incorrect fix for     CVE-2011-4108. (CVE-2012-0050)

  - The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c     in OpenSSL before 0.9.8v, 1.0.0 before 1.0.0i, and 1.0.1     before 1.0.1a does not properly interpret integer data,     which allows remote attackers to conduct buffer overflow     attacks, and cause a denial of service (memory     corruption) or possibly have unspecified other impact,     via crafted DER data, as demonstrated by an X.509     certificate or an RSA public key. (CVE-2012-2110)

  - The ssl3_take_mac function in ssl/s3_both.c in OpenSSL     1.0.1 before 1.0.1f allows remote TLS servers to cause a     denial of service (NULL pointer dereference and     application crash) via a crafted Next Protocol     Negotiation record in a TLS handshake. (CVE-2013-4353)

  - The ssl_get_algorithm2 function in ssl/s3_lib.c in     OpenSSL before 1.0.2 obtains a certain version number     from an incorrect data structure, which allows remote     attackers to cause a denial of service (daemon crash)     via crafted traffic from a TLS 1.2 client.
    (CVE-2013-6449)

  - The DTLS retransmission implementation in OpenSSL 1.0.0     before 1.0.0l and 1.0.1 before 1.0.1f does not properly     maintain data structures for digest and encryption     contexts, which might allow man-in-the-middle attackers     to trigger the use of a different context and cause a     denial of service (application crash) by interfering     with packet delivery, related to ssl/d1_both.c and     ssl/t1_enc.c. (CVE-2013-6450)

  - 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)

  - A flaw was found in the way SSL 3.0 handled padding     bytes when decrypting messages encrypted using block     ciphers in cipher block chaining (CBC) mode. This flaw     allows a man-in-the-middle (MITM) attacker to decrypt a     selected byte of a cipher text in as few as 256 tries if     they are able to force a victim application to     repeatedly send the same data over newly created SSL 3.0     connections. (CVE-2014-3566)

  - A flaw was found in the way the DES/3DES cipher was used     as part of the TLS/SSL protocol. A man-in-the-middle     attacker could use this flaw to recover some plaintext     data by capturing large amounts of encrypted traffic     between TLS/SSL server and client if the communication     used a DES/3DES based ciphersuite. (CVE-2016-2183)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
