https://notcve.org/view.php?id=CVE-2016-2125
It was found that Samba before versions 4.5.3, 4.4.8, 4.3.13 always requested forwardable tickets when using Kerberos authentication. A service to which Samba authenticated using Kerberos could subsequently use the ticket to impersonate Samba to other services or domain users. Se ha descubierto que Samba, en versiones anteriores a la 4.5.3, 4.4.8 y 4.3.13, siempre solicitaba tickets que podían reenviarse al emplear la autenticación de Kerberos. Un servicio al que Samba se ha autenticado con Kerberos podría emplear el ticket para suplantar Samba con otros usuarios de servicios o dominios. It was found that Samba always requested forwardable tickets when using Kerberos authentication. • http://rhn.redhat.com/errata/RHSA-2017-0494.html http://rhn.redhat.com/errata/RHSA-2017-0495.html http://rhn.redhat.com/errata/RHSA-2017-0662.html http://rhn.redhat.com/errata/RHSA-2017-0744.html http://www.securityfocus.com/bid/94988 http://www.securitytracker.com/id/1037494 https://access.redhat.com/errata/RHSA-2017:1265 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-2125 https://www.samba.org/samba/security/CVE-2016-2125.html https://access.redhat.c • CWE-20: Improper Input Validation CWE-287: Improper Authentication •

SELinux policycoreutils allows local users to execute arbitrary commands outside of the sandbox via a crafted TIOCSTI ioctl call. SELinux policycoreutils permite a usuarios locales ejecutar comandos arbitrarios fuera de la sandbox a través de una llamada ioctl TIOCSTI manipulada. It was found that the sandbox tool provided in policycoreutils was vulnerable to a TIOCSTI ioctl attack. A specially crafted program executed via the sandbox command could use this flaw to execute arbitrary commands in the context of the parent shell, escaping the sandbox. • http://rhn.redhat.com/errata/RHSA-2016-2702.html http://rhn.redhat.com/errata/RHSA-2017-0535.html http://rhn.redhat.com/errata/RHSA-2017-0536.html http://www.openwall.com/lists/oss-security/2016/09/25/1 http://www.securityfocus.com/bid/93156 http://www.securitytracker.com/id/1037283 https://github.com/SELinuxProject/selinux/commit/acca96a135a4d2a028ba9b636886af99c0915379 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UPRNK3PWMAVNJZ53YW5GOEOGJSFNAQIF https:& • CWE-284: Improper Access Control •
CVSS: 4.9EPSS: 0%CPEs: 19EXPL: 0CVE-2016-5011 – util-linux: Extended partition loop in MBR partition table leads to DOS
https://notcve.org/view.php?id=CVE-2016-5011
The parse_dos_extended function in partitions/dos.c in the libblkid library in util-linux allows physically proximate attackers to cause a denial of service (memory consumption) via a crafted MSDOS partition table with an extended partition boot record at zero offset. La función parse_dos_extended en partitions/dos.c en la biblioteca libblkid en util-linux permite a atacantes físicamente próximos provocar una denegación de servicio (consumo de memoria) a través de una tabla de particiones MSDOS manipulada con un registro de arranque de partición extendida en desplazamiento cero. It was found that util-linux's libblkid library did not properly handle Extended Boot Record (EBR) partitions when reading MS-DOS partition tables. An attacker with physical USB access to a protected machine could insert a storage device with a specially crafted partition table that could, for example, trigger an infinite loop in systemd-udevd, resulting in a denial of service on that machine. • http://rhn.redhat.com/errata/RHSA-2016-2605.html http://www-01.ibm.com/support/docview.wss?uid=isg3T1024543 http://www-01.ibm.com/support/docview.wss?uid=nas8N1021801 http://www.openwall.com/lists/oss-security/2016/07/11/2 http://www.securityfocus.com/bid/91683 http://www.securitytracker.com/id/1036272 https://git.kernel.org/pub/scm/utils/util-linux/util-linux.git/commit/?id=7164a1c3 https://access.redhat.com/security/cve/CVE-2016-5011 https://bugzilla.redhat. •

https://notcve.org/view.php?id=CVE-2015-5160
libvirt before 2.2 includes Ceph credentials on the qemu command line when using RADOS Block Device (aka RBD), which allows local users to obtain sensitive information via a process listing. libvirt en versiones anteriores a la 2.2 incluye las credenciales de Ceph en la línea de comandos qemu cuando se utiliza RADOS Block Device (también conocido como RBD), lo que permite a los usuarios locales obtener información sensible mediante un listado de procesos. It was found that the libvirt daemon, when using RBD (RADOS Block Device), leaked private credentials to the process list. A local attacker could use this flaw to perform certain privileged operations within the cluster. • http://rhn.redhat.com/errata/RHSA-2016-2577.html http://www.openwall.com/lists/oss-security/2017/07/21/3 https://bugs.launchpad.net/ossn/+bug/1686743 https://bugzilla.redhat.com/show_bug.cgi?id=1245647 https://wiki.openstack.org/wiki/OSSN/OSSN-0079 https://access.redhat.com/security/cve/CVE-2015-5160 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
