CVE-2018-14719 – jackson-databind: arbitrary code execution in blaze-ds-opt and blaze-ds-core classes
https://notcve.org/view.php?id=CVE-2018-14719
FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to execute arbitrary code by leveraging failure to block the blaze-ds-opt and blaze-ds-core classes from polymorphic deserialization. Las versiones 2.x de FasterXML jackson-databind anteriores a la 2.9.7 podrían permitir a los atacantes remotos ejecutar código arbitrario aprovechando un fallo para bloquear las clases blaze-ds-opt y blaze-ds-core de deserialización polimórfica. A flaw was discovered in jackson-databind, where it would permit polymorphic deserialization of a malicious object using blaze classes. An attacker could use this flaw to execute arbitrary code. • https://access.redhat.com/errata/RHBA-2019:0959 https://access.redhat.com/errata/RHSA-2019:0782 https://access.redhat.com/errata/RHSA-2019:0877 https://access.redhat.com/errata/RHSA-2019:1782 https://access.redhat.com/errata/RHSA-2019:1797 https://access.redhat.com/errata/RHSA-2019:1822 https://access.redhat.com/errata/RHSA-2019:1823 https://access.redhat.com/errata/RHSA-2019:2804 https://access.redhat.com/errata/RHSA-2019:2858 https://access.redhat.com/errata/RHSA • CWE-502: Deserialization of Untrusted Data •
CVE-2018-17246
https://notcve.org/view.php?id=CVE-2018-17246
Kibana versions before 6.4.3 and 5.6.13 contain an arbitrary file inclusion flaw in the Console plugin. An attacker with access to the Kibana Console API could send a request that will attempt to execute javascript code. This could possibly lead to an attacker executing arbitrary commands with permissions of the Kibana process on the host system. Kibana, en versiones anteriores a la 6.4.3 y la 5.6.13, contiene un error de inclusión de archivos arbitrarios en el plugin Console. Un atacante con acceso a la API de la consola de Kibana podría enviar una petición que intentará ejecutar código JavaScript. • https://github.com/mpgn/CVE-2018-17246 http://www.securityfocus.com/bid/106285 https://access.redhat.com/errata/RHBA-2018:3743 https://discuss.elastic.co/t/elastic-stack-6-4-3-and-5-6-13-security-update/155594 https://www.elastic.co/community/security • CWE-73: External Control of File Name or Path CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
CVE-2018-20102 – haproxy: Out-of-bounds read in dns.c:dns_validate_dns_response() allows for memory disclosure
https://notcve.org/view.php?id=CVE-2018-20102
An out-of-bounds read in dns_validate_dns_response in dns.c was discovered in HAProxy through 1.8.14. Due to a missing check when validating DNS responses, remote attackers might be able read the 16 bytes corresponding to an AAAA record from the non-initialized part of the buffer, possibly accessing anything that was left on the stack, or even past the end of the 8193-byte buffer, depending on the value of accepted_payload_size. Se ha descubierto una lectura fuera de límites en dns_validate_dns_response en dns.c en HAProxy hasta la versión 1.8.14. Debido a la falta de una comprobación al validar respuestas DNS, los atacantes remotos pueden leer los 16 bits que corresponden a un registro AAAA de la parte no inicializada del búfer, pudiendo acceder a cualquier cosa que haya quedado en la pila, o incluso más allá del final del búfer de 8193 bytes, dependiendo del valor de accepted_payload_size. • http://git.haproxy.org/?p=haproxy.git%3Ba=commit%3Bh=efbbdf72992cd20458259962346044cafd9331c0 http://www.securityfocus.com/bid/106223 https://access.redhat.com/errata/RHBA-2019:0326 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2019:1436 https://lists.debian.org/debian-lts-announce/2022/05/msg00045.html https://usn.ubuntu.com/3858-1 https://access.redhat.com/security/cve/CVE-2018-20102 https://bugzilla.redhat.com/show_bug.cgi?id=1658874 • CWE-125: Out-of-bounds Read •
CVE-2018-20103 – haproxy: Infinite recursion via crafted packet allows stack exhaustion and denial of service
https://notcve.org/view.php?id=CVE-2018-20103
An issue was discovered in dns.c in HAProxy through 1.8.14. In the case of a compressed pointer, a crafted packet can trigger infinite recursion by making the pointer point to itself, or create a long chain of valid pointers resulting in stack exhaustion. Se ha descubierto un problema en dns.c en HAProxy hasta la versión 1.8.14. En el caso de un puntero comprimido, un paquete manipulado puede desencadenar una recursión infinita haciendo que el puntero se señale a sí mismo o cree una cadena larga de punteros válidos, lo que resulta en el agotamiento de la pila. • http://git.haproxy.org/?p=haproxy.git%3Ba=commit%3Bh=58df5aea0a0c926b2238f65908f5e9f83d1cca25 http://www.securityfocus.com/bid/106280 https://access.redhat.com/errata/RHBA-2019:0326 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2019:1436 https://lists.debian.org/debian-lts-announce/2022/05/msg00045.html https://usn.ubuntu.com/3858-1 https://access.redhat.com/security/cve/CVE-2018-20103 https://bugzilla.redhat.com/show_bug.cgi?id=1658876 • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2018-18397 – kernel: userfaultfd bypasses tmpfs file permissions
https://notcve.org/view.php?id=CVE-2018-18397
The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c. La implementación de userfaultfd en el kernel de Linux en versiones anteriores a la 4.17 gestiona de manera incorrecta para ciertas llamadas ioctl UFFDIO_, tal y como queda demostrado al permitir que usuarios locales escriban datos en huecos en un archivo tmpfs (si el usuario tiene acceso de solo lectura a dicho archivo que contiene huecos). Esto está relacionado con fs/userfaultfd.c y mm/userfaultfd.c. A flaw was found in the Linux kernel with files on tmpfs and hugetlbfs. An attacker is able to bypass file permissions on filesystems mounted with tmpfs/hugetlbs to modify a file and possibly disrupt normal system behavior. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=29ec90660d68bbdd69507c1c8b4e33aa299278b1 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2019:0163 https://access.redhat.com/errata/RHSA-2019:0202 https://access.redhat.com/errata/RHSA-2019:0324 https://access.redhat.com/errata/RHSA-2019:0831 https://bugs.chromium.org/p/project-zero/issues/detail?id=1700 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.14.87& • CWE-20: Improper Input Validation CWE-863: Incorrect Authorization •
