CVE-2016-4470 – kernel: Uninitialized variable in request_key handling causes kernel crash in error handling path
https://notcve.org/view.php?id=CVE-2016-4470
The key_reject_and_link function in security/keys/key.c in the Linux kernel through 4.6.3 does not ensure that a certain data structure is initialized, which allows local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command. La función key_reject_and_link en security/keys/key.c en el kernel de Linux hasta la versión 4.6.3 no asegura que cierta estructura de datos esté inicializada, lo que permite a usuarios locales provocar una denegación de servicio (caída del sistema) a través de vectores involucrando un comando keyctl request2 manipulado. A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=38327424b40bcebe2de92d07312c89360ac9229a http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00009.html http://lists.opensuse.org • CWE-253: Incorrect Check of Function Return Value •
CVE-2016-2141 – JGroups: Authorization bypass
https://notcve.org/view.php?id=CVE-2016-2141
It was found that JGroups did not require necessary headers for encrypt and auth protocols from new nodes joining the cluster. An attacker could use this flaw to bypass security restrictions, and use this vulnerability to send and receive messages within the cluster, leading to information disclosure, message spoofing, or further possible attacks. JGroups en versiones anteriores a 4.0 no solicita las cabeceras adecuadas para los protocolos ENCRYPT y AUTH desde los nodos uniéndose al grupo, lo que permite a atacantes remotos eludir las restricciones de seguridad y enviar y recibir mensajes dentro del grupo a través de vectores no especificados. • http://rhn.redhat.com/errata/RHSA-2016-1435.html http://rhn.redhat.com/errata/RHSA-2016-1439.html http://rhn.redhat.com/errata/RHSA-2016-2035.html http://www.securityfocus.com/bid/91481 http://www.securitytracker.com/id/1036165 https://access.redhat.com/errata/RHSA-2016:1345 https://access.redhat.com/errata/RHSA-2016:1346 https://access.redhat.com/errata/RHSA-2016:1347 https://access.redhat.com/errata/RHSA-2016:1374 https://access.redhat.com/errata/RHSA-2016:1376& •
CVE-2016-4428 – python-django-horizon: XSS in client side template
https://notcve.org/view.php?id=CVE-2016-4428
Cross-site scripting (XSS) vulnerability in OpenStack Dashboard (Horizon) 8.0.1 and earlier and 9.0.0 through 9.0.1 allows remote authenticated users to inject arbitrary web script or HTML by injecting an AngularJS template in a dashboard form. Vulnerabilidad de XSS en OpenStack Dashboard (Horizon) 8.0.1 y versiones anteriores y 9.0.0 hasta la versión 9.0.1 permite a usuarios remotos autenticados inyectar secuencias de comandos web o HTML arbitrario inyectando una plantilla AngularJS en un formulario del cuadro de mandos. A DOM-based, cross-site scripting vulnerability was found in the OpenStack dashboard, where user input was not filtered correctly. An authenticated dashboard user could exploit the flaw by injecting an AngularJS template into a dashboard form (for example, using an image's description), triggering the vulnerability when another user browsed the affected page. As a result, this flaw could result in user accounts being compromised (for example, user-access credentials being stolen). • http://www.debian.org/security/2016/dsa-3617 http://www.openwall.com/lists/oss-security/2016/06/17/4 https://access.redhat.com/errata/RHSA-2016:1268 https://access.redhat.com/errata/RHSA-2016:1269 https://access.redhat.com/errata/RHSA-2016:1270 https://access.redhat.com/errata/RHSA-2016:1271 https://access.redhat.com/errata/RHSA-2016:1272 https://bugs.launchpad.net/horizon/+bug/1567673 https://review.openstack.org/329996 https://review.openstack.org/329997 https • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-2016-2178 – openssl: Non-constant time codepath followed for certain operations in DSA implementation
https://notcve.org/view.php?id=CVE-2016-2178
The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack. La función dsa_sign_setup en crypto/dsa/dsa_ossl.c en OpenSSL hasta la versión 1.0.2h no asegura correctamente la utilización de operaciones de tiempo constante, lo que facilita a usuarios locales descubrir una clave privada DSA a través de un ataque de sincronización de canal lateral. It was discovered that OpenSSL did not always use constant time operations when computing Digital Signature Algorithm (DSA) signatures. A local attacker could possibly use this flaw to obtain a private DSA key belonging to another user or service running on the same system. • http://eprint.iacr.org/2016/594.pdf http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org& • CWE-203: Observable Discrepancy CWE-385: Covert Timing Channel •
CVE-2016-2177 – openssl: Possible integer overflow vulnerabilities in codebase
https://notcve.org/view.php?id=CVE-2016-2177
OpenSSL through 1.0.2h incorrectly uses pointer arithmetic for heap-buffer boundary checks, which might allow remote attackers to cause a denial of service (integer overflow and application crash) or possibly have unspecified other impact by leveraging unexpected malloc behavior, related to s3_srvr.c, ssl_sess.c, and t1_lib.c. OpenSSL hasta la versión 1.0.2h no utiliza correctamente la aritmética de puntero para comprobaciones de límites de buffer de memoria dinámica, lo que podría permitir a atacantes remotos provocar una denegación de servicio (desbordamiento de entero y caída de aplicación) o posiblemente tener otro impacto no especificado aprovechando un comportamiento malloc no esperado, relacionado con s3_srvr.c, ssl_sess.c, y t1_lib.c. Multiple integer overflow flaws were found in the way OpenSSL performed pointer arithmetic. A remote attacker could possibly use these flaws to cause a TLS/SSL server or client using OpenSSL to crash. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00011.h • CWE-190: Integer Overflow or Wraparound •
