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 •
CVE-2018-5527
https://notcve.org/view.php?id=CVE-2018-5527
On BIG-IP 13.1.0-13.1.0.7, a remote attacker using undisclosed methods against virtual servers configured with a Client SSL or Server SSL profile that has the SSL Forward Proxy feature enabled can force the Traffic Management Microkernel (tmm) to leak memory. As a result, system memory usage increases over time, which may eventually cause a decrease in performance or a system reboot due to memory exhaustion. En BIG-IP 13.1.0-13.1.0.7, un atacante remoto que emplea métodos no revelados contra servidores virtuales configurados con un perfil Client SSL o Server SSL con la característica SSL Forward Proxy habilitada puede forzar al TMM (Traffic Management Microkernel) a filtrar memoria. Como resultado, el uso de la memoria del sistema aumenta con el tiempo, lo que podría provocar un descenso del rendimiento o un reinicio del sistema debido al agotamiento de memoria. • http://www.securitytracker.com/id/1041196 https://support.f5.com/csp/article/K20134942 • CWE-772: Missing Release of Resource after Effective Lifetime •

CVE-2018-5513
https://notcve.org/view.php?id=CVE-2018-5513
On F5 BIG-IP 13.1.0-13.1.0.3, 13.0.0, 12.1.0-12.1.3.3, 11.6.1-11.6.3.1, 11.5.1-11.5.5, or 11.2.1, a malformed TLS handshake causes TMM to crash leading to a disruption of service. This issue is only exposed on the data plane when Proxy SSL configuration is enabled. The control plane is not impacted by this issue. En F5 BIG-IP, 13.1.0-13.1.0.3, 13.0.0, 12.1.0-12.1.3.3, 11.6.1-11.6.3.1, 11.5.1-11.5.5 o en la versión 11.2.1, un handshake TLS mal formado hace que TMM se cierre inesperadamente, lo que conduce a una interrupción del servicio. Este problema solo se expone en el plano de datos cuando la configuración Proxy SSL está habilitada. • http://www.securitytracker.com/id/1041017 https://support.f5.com/csp/article/K46940010 • CWE-20: Improper Input Validation •
