CVE-2017-17485 – jackson-databind: Unsafe deserialization due to incomplete black list (incomplete fix for CVE-2017-15095)
https://notcve.org/view.php?id=CVE-2017-17485
FasterXML jackson-databind through 2.8.10 and 2.9.x through 2.9.3 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 deserialization flaw. This is exploitable by sending maliciously crafted JSON input to the readValue method of the ObjectMapper, bypassing a blacklist that is ineffective if the Spring libraries are available in the classpath. FasterXML jackson-databind hasta la versión 2.8.10 y 2.9.x hasta la 2.9.3 permite que se ejecute código de manera remota y no autenticada debido a una solución incompleta de la vulnerabilidad de deserialización CVE-2017-7525. Esto es explotable enviando una entrada JSON manipulada maliciosamente al método readValue de ObjectMapper, omitiendo una lista negra que no es efectiva si las librerías Spring están disponibles en el classpath. A deserialization flaw was discovered in the jackson-databind which could allow an unauthenticated user to perform code execution by sending maliciously crafted input to the readValue method of ObjectMapper. • https://github.com/Al1ex/CVE-2017-17485 https://github.com/tafamace/CVE-2017-17485 http://www.securityfocus.com/archive/1/541652/100/0/threaded https://access.redhat.com/errata/RHSA-2018:0116 https://access.redhat.com/errata/RHSA-2018:0342 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/RHS • CWE-502: Deserialization of Untrusted Data •
CVE-2017-12159 – keycloak: CSRF token fixation
https://notcve.org/view.php?id=CVE-2017-12159
It was found that the cookie used for CSRF prevention in Keycloak was not unique to each session. An attacker could use this flaw to gain access to an authenticated user session, leading to possible information disclosure or further attacks. Se ha descubierto que la cookie empleada para la prevención de CSRF en Keycloak no era única para cada sesión. Un atacante podría usar este fallo para obtener acceso a una sesión de un usuario autenticado, conduciendo a una posible divulgación de información o a más ataques. • http://www.securityfocus.com/bid/101601 https://access.redhat.com/errata/RHSA-2017:2904 https://access.redhat.com/errata/RHSA-2017:2905 https://access.redhat.com/errata/RHSA-2017:2906 https://bugzilla.redhat.com/show_bug.cgi?id=1484111 https://access.redhat.com/security/cve/CVE-2017-12159 • CWE-613: Insufficient Session Expiration •

CVE-2017-13704
https://notcve.org/view.php?id=CVE-2017-13704
In dnsmasq before 2.78, if the DNS packet size does not match the expected size, the size parameter in a memset call gets a negative value. As it is an unsigned value, memset ends up writing up to 0xffffffff zero's (0xffffffffffffffff in 64 bit platforms), making dnsmasq crash. En las versiones anteriores a la 2.78 de dnsmasq, si el tamaño del paquete DNS no coincide con el tamaño esperado, el parámetro size en una llamada memset obtiene un valor negativo. Como es un valor sin signo, memset acaba escribiendo hasta 0xffffffff ceros (0xffffffffffffffff en plataformas de 64 bits), haciendo que dnsmasq se cierre de manera inesperada. • http://thekelleys.org.uk/dnsmasq/CHANGELOG http://thekelleys.org.uk/gitweb/?p=dnsmasq.git%3Ba=commit%3Bh=63437ffbb58837b214b4b92cb1c54bc5f3279928 http://www.securityfocus.com/bid/101085 http://www.securityfocus.com/bid/101977 http://www.securitytracker.com/id/1039474 https://access.redhat.com/security/vulnerabilities/3199382 https://cert-portal.siemens.com/productcert/pdf/ssa-689071.pdf https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4TK6DWC53WSU6633EVZL7H4PCWBYHMHK https:& • CWE-20: Improper Input Validation •
CVE-2017-14492 – Dnsmasq < 2.78 - Heap Overflow
https://notcve.org/view.php?id=CVE-2017-14492
Heap-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted IPv6 router advertisement request. Un desbordamiento de búfer basado en memoria dinámica (heap) en dnsmasq en versiones anteriores a la 2.78 permite a los atacantes provocar una denegación de servicio (cierre inesperado) o ejecutar código arbitrario mediante una petición manipulada de anuncio de router IPv6. A heap buffer overflow was discovered in dnsmasq in the IPv6 router advertisement (RA) handling code. An attacker on the local network segment could send crafted RAs to dnsmasq which would cause it to crash or, potentially, execute arbitrary code. This issue only affected configurations using one of these options: enable-ra, ra-only, slaac, ra-names, ra-advrouter, or ra-stateless. • https://www.exploit-db.com/exploits/42942 http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00006.html http://nvidia.custhelp.com/app/answers/detail/a_id/4561 http://thekelleys.org.uk/dnsmasq/CHANGELOG http://thekelleys.org.uk/gitweb/?p=dnsmasq.git%3Ba=commit%3Bh=24036ea507862c7b7898b68289c8130f85599c10 http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2017-005.txt http://www.debian.org/security/2017/dsa-3989 http://www.securityfocus.com/bid/101085 http://www.securitytrac • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
