CVE-2018-5390 – Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service
https://notcve.org/view.php?id=CVE-2018-5390
Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. El kernel de Linux en versiones 4.9 y siguientes pueden forzarse a realizar llamadas muy caras a tcp_collapse_ofo_queue() y tcp_prune_ofo_queue() para cada paquete entrante, lo que puede conducir a una denegación de servicio. A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2018-004.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20181031-02-linux-en http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/104976 http://www.securitytracker.com/id/1041424 http://www.securitytracker.com/id/1041434 https://access.redhat.co • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-10897 – yum-utils: reposync: improper path validation may lead to directory traversal
https://notcve.org/view.php?id=CVE-2018-10897
A directory traversal issue was found in reposync, a part of yum-utils, where reposync fails to sanitize paths in remote repository configuration files. If an attacker controls a repository, they may be able to copy files outside of the destination directory on the targeted system via path traversal. If reposync is running with heightened privileges on a targeted system, this flaw could potentially result in system compromise via the overwriting of critical system files. Version 1.1.31 and older are believed to be affected. Se ha detectado un problema de salto de directorio en reposync, de yum-utils, en el que reposync falla a la hora de sanear rutas en los archivos de configuración del repositorio remoto. • http://www.securitytracker.com/id/1041594 https://access.redhat.com/errata/RHSA-2018:2284 https://access.redhat.com/errata/RHSA-2018:2285 https://access.redhat.com/errata/RHSA-2018:2626 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10897 https://github.com/rpm-software-management/yum-utils/commit/6a8de061f8fdc885e74ebe8c94625bf53643b71c https://github.com/rpm-software-management/yum-utils/commit/7554c0133eb830a71dc01846037cc047d0acbc2c https://github.com/rpm-software-management/yum-utils/pull/43 https • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •
CVE-2018-10862 – wildfly-core: Path traversal can allow the extraction of .war archives to write arbitrary files (Zip Slip)
https://notcve.org/view.php?id=CVE-2018-10862
WildFly Core before version 6.0.0.Alpha3 does not properly validate file paths in .war archives, allowing for the extraction of crafted .war archives to overwrite arbitrary files. This is an instance of the 'Zip Slip' vulnerability. WildFly Core en versiones anteriores a la 6.0.0.0.Alpha3 no valida correctamente las rutas de los archivos en los archivos .war, lo que permite la extracción de archivos .war manipulados para sobrescribir archivos arbitrarios. Este es un ejemplo de la vulnerabilidad 'Zip Slip'. It was found that the explode function of the deployment utility in jboss-cli and console that allows extraction of files from an archive does not perform necessary validation for directory traversal. • https://access.redhat.com/errata/RHSA-2018:2276 https://access.redhat.com/errata/RHSA-2018:2277 https://access.redhat.com/errata/RHSA-2018:2279 https://access.redhat.com/errata/RHSA-2018:2423 https://access.redhat.com/errata/RHSA-2018:2424 https://access.redhat.com/errata/RHSA-2018:2425 https://access.redhat.com/errata/RHSA-2018:2428 https://access.redhat.com/errata/RHSA-2018:2643 https://access.redhat.com/errata/RHSA-2019:0877 https://bugzilla.redhat.com/show_bug. • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVE-2018-10875 – ansible: ansible.cfg is being read from current working directory allowing possible code execution

A flaw was found in ansible. ansible.cfg is read from the current working directory which can be altered to make it point to a plugin or a module path under the control of an attacker, thus allowing the attacker to execute arbitrary code. Se ha encontrado un error en ansible. ansible.cfg se lee desde el directorio de trabajo actual, que puede alterarse para hacer que señale a un plugin o una ruta de módulo bajo el control de un atacante, permitiendo que el atacante ejecute código arbitrario.

CVE-2018-13405 – Linux (Ubuntu) - Other Users coredumps Can Be Read via setgid Directory and killpriv Bypass
https://notcve.org/view.php?id=CVE-2018-13405
The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID. La función inode_init_owner en fs/inode.c en el kernel de Linux hasta la versión 3.16 permite a los usuarios locales crear archivos con una propiedad de grupo no deseada, en un escenario donde un directorio es SGID a un cierto grupo y es escribible por un usuario que no es miembro de ese grupo. • https://www.exploit-db.com/exploits/45033 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0fa3ecd87848c9c93c2c828ef4c3a8ca36ce46c7 http://openwall.com/lists/oss-security/2018/07/13/2 http://www.securityfocus.com/bid/106503 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://access.redhat.com/errata/RHSA-2019:0717 https://access.redhat.com/errata/RHSA- • CWE-269: Improper Privilege Management CWE-284: Improper Access Control •
