CVSS: 4.3EPSS: 2%CPEs: 16EXPL: 0CVE-2018-1050 – samba: NULL pointer dereference in printer server process
https://notcve.org/view.php?id=CVE-2018-1050
All versions of Samba from 4.0.0 onwards are vulnerable to a denial of service attack when the RPC spoolss service is configured to be run as an external daemon. Missing input sanitization checks on some of the input parameters to spoolss RPC calls could cause the print spooler service to crash. Todas las versiones de Samba, desde la 4.0.0 en adelante, son vulnerables a un ataque de denegación de servicio (DoS) cuando el servicio RPC spoolss se configura para ejecutarse como demonio externo. La falta de comprobaciones de saneamiento de entradas en algunos de los parámetros de entrada en las llamadas RPC spoolss podrían provocar que el servicio print spooler se cierre inesperadamente. A null pointer dereference flaw was found in Samba RPC external printer service. • http://www.securityfocus.com/bid/103387 http://www.securitytracker.com/id/1040493 https://access.redhat.com/errata/RHSA-2018:1860 https://access.redhat.com/errata/RHSA-2018:1883 https://access.redhat.com/errata/RHSA-2018:2612 https://access.redhat.com/errata/RHSA-2018:2613 https://access.redhat.com/errata/RHSA-2018:3056 https://bugzilla.redhat.com/show_bug.cgi?id=1538771 https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6. • CWE-476: NULL Pointer Dereference •

The resv_map_release function in mm/hugetlb.c in the Linux kernel through 4.15.7 allows local users to cause a denial of service (BUG) via a crafted application that makes mmap system calls and has a large pgoff argument to the remap_file_pages system call.

CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 0CVE-2017-7518 – Kernel: KVM: debug exception via syscall emulation
https://notcve.org/view.php?id=CVE-2017-7518
A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux guests are not affected by this. Se ha detectado un error en el kernel de Linux en versiones anteriores a la 4.12 en la forma en la que el módulo KVM procesó el bit trap flag(TF) en EFLAGS durante la emulación de la instrucción de la llamada del sistema, lo que conduce a que se lance una excepción de depuración (#DB) en la pila invitada. Un usuario/proceso en un invitado podría utilizar este error para escalar sus privilegios en el invitado. • http://www.openwall.com/lists/oss-security/2017/06/23/5 http://www.securityfocus.com/bid/99263 http://www.securitytracker.com/id/1038782 https://access.redhat.com/articles/3290921 https://access.redhat.com/errata/RHSA-2018:0395 https://access.redhat.com/errata/RHSA-2018:0412 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-7518 https://usn.ubuntu.com/3619-1 https://usn.ubuntu.com/3619-2 https://usn.ubuntu.com/3754-1 https://www.debian.org/security&# • CWE-250: Execution with Unnecessary Privileges CWE-755: Improper Handling of Exceptional Conditions •

MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to circumvent a DN containership check by supplying both a "linkdn" and "containerdn" database argument, or by supplying a DN string which is a left extension of a container DN string but is not hierarchically within the container DN.
