CVE-2018-5968 – jackson-databind: unsafe deserialization due to incomplete blacklist (incomplete fix for CVE-2017-7525 and CVE-2017-17485)
https://notcve.org/view.php?id=CVE-2018-5968
FasterXML jackson-databind through 2.8.11 and 2.9.x through 2.9.3 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 and CVE-2017-17485 deserialization flaws. This is exploitable via two different gadgets that bypass a blacklist. FasterXML jackson-databind, hasta la versión 2.8.11 y las versiones 2.9.x hasta la 2.9.3, permite la ejecución remota de código sin autenticar debido a una solución incompleta para los errores de deserialización CVE-2017-7525 y CVE-2017-17485. Esto es explotable mediante dos gadgets diferentes que omiten una lista negra. A deserialization flaw was discovered in the jackson-databind that could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper. • https://access.redhat.com/errata/RHSA-2018:0478 https://access.redhat.com/errata/RHSA-2018:0479 https://access.redhat.com/errata/RHSA-2018:0480 https://access.redhat.com/errata/RHSA-2018:0481 https://access.redhat.com/errata/RHSA-2018:1525 https://access.redhat.com/errata/RHSA-2019:2858 https://access.redhat.com/errata/RHSA-2019:3149 https://github.com/FasterXML/jackson-databind/issues/1899 https://security.netapp.com/advisory/ntap-20180423-0002 https://support.hpe.com/h • CWE-184: Incomplete List of Disallowed Inputs CWE-502: Deserialization of Untrusted Data •
CVE-2017-1000410 – kernel: Stack information leak in the EFS element
https://notcve.org/view.php?id=CVE-2017-1000410
The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels which were built with the above mitigations. • http://seclists.org/oss-sec/2017/q4/357 http://www.securityfocus.com/bid/102101 https://access.redhat.com/errata/RHSA-2018:0654 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2018:1130 https://access.redhat.com/errata/RHSA-2018:1170 https://access.redhat.com/errata/RHSA-2018:1319 https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2017-7536 – hibernate-validator: Privilege escalation when running under the security manager
https://notcve.org/view.php?id=CVE-2017-7536
In Hibernate Validator 5.2.x before 5.2.5 final, 5.3.x, and 5.4.x, it was found that when the security manager's reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. By allowing the calling code to access those private members without the permission an attacker may be able to validate an invalid instance and access the private member value via ConstraintViolation#getInvalidValue(). En Hibernate Validator 5.2.x anteriores a 5.2.5 final, 5.3.x y 5.4.x, se ha detectado que cuando los permisos reflectivos del gestor de seguridad, el cual accede a los miembros privados de la clase, se conceden a Hibernate Validator, podría ocurrir un escalado de privilegios. Permitiendo que el código de llamada acceda a esos miembros privados sin ningún permiso, el atacante podría validar una instancia no válida y acceder al valor del miembro privado mediante ConstraintViolation#getInvalidValue(). It was found that when the security manager's reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. • http://www.securityfocus.com/bid/101048 http://www.securitytracker.com/id/1039744 https://access.redhat.com/errata/RHSA-2017:2808 https://access.redhat.com/errata/RHSA-2017:2809 https://access.redhat.com/errata/RHSA-2017:2810 https://access.redhat.com/errata/RHSA-2017:2811 https://access.redhat.com/errata/RHSA-2017:3141 https://access.redhat.com/errata/RHSA-2017:3454 https://access.redhat.com/errata/RHSA-2017:3455 https://access.redhat.com/errata/RHSA-2017:3456 https: • CWE-470: Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') CWE-592: DEPRECATED: Authentication Bypass Issues •
CVE-2017-7539 – Qemu: qemu-nbd crashes due to undefined I/O coroutine
https://notcve.org/view.php?id=CVE-2017-7539
An assertion-failure flaw was found in Qemu before 2.10.1, in the Network Block Device (NBD) server's initial connection negotiation, where the I/O coroutine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service. Se ha detectado un fallo de aserción en Qemu en versiones anteriores a la 2.10.1 en la negociación de conexión inicial de los servidores de NBD (Network Block Device) en el que la corrutina I/O no estaba definida. Esto podría provocar el cierre inesperado del servidor qemu-nbd si un cliente envía datos no esperados durante la negociación de la conexión. • http://www.openwall.com/lists/oss-security/2017/07/21/4 http://www.securityfocus.com/bid/99944 https://access.redhat.com/errata/RHSA-2017:2628 https://access.redhat.com/errata/RHSA-2017:3466 https://access.redhat.com/errata/RHSA-2017:3470 https://access.redhat.com/errata/RHSA-2017:3471 https://access.redhat.com/errata/RHSA-2017:3472 https://access.redhat.com/errata/RHSA-2017:3473 https://access.redhat.com/errata/RHSA-2017:3474 https://bugzilla.redhat.com/show_b • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •
CVE-2017-7525 – jackson-databind: Deserialization vulnerability via readValue method of ObjectMapper
