CVE-2018-6764 – libvirt: guest could inject executable code via libnss_dns.so loaded by libvirt_lxc before init
https://notcve.org/view.php?id=CVE-2018-6764
util/virlog.c in libvirt does not properly determine the hostname on LXC container startup, which allows local guest OS users to bypass an intended container protection mechanism and execute arbitrary commands via a crafted NSS module. util/virlog.c en libvirt no determina correctamente el nombre de host en el arranque del contenedor LXC, lo que permite que usuarios locales invitados del sistema operativo omitan un mecanismo de protección de contenedor planeado y ejecuten comandos arbitrarios mediante un módulo NSS manipulado. • http://www.ubuntu.com/usn/USN-3576-1 https://access.redhat.com/errata/RHSA-2018:3113 https://www.debian.org/security/2018/dsa-4137 https://www.redhat.com/archives/libvir-list/2018-February/msg00239.html https://access.redhat.com/security/cve/CVE-2018-6764 https://bugzilla.redhat.com/show_bug.cgi?id=1541444 • CWE-179: Incorrect Behavior Order: Early Validation CWE-346: Origin Validation Error •
CVE-2018-6056 – chromium-browser: incorrect derived class instantiation in v8

CVE-2018-7225 – libvncserver: Improper input sanitization in rfbProcessClientNormalMessage in rfbserver.c
https://notcve.org/view.php?id=CVE-2018-7225
An issue was discovered in LibVNCServer through 0.9.11. rfbProcessClientNormalMessage() in rfbserver.c does not sanitize msg.cct.length, leading to access to uninitialized and potentially sensitive data or possibly unspecified other impact (e.g., an integer overflow) via specially crafted VNC packets. Se ha descubierto un problema en LibVNCServer hasta la versión 0.9.11. rfbProcessClientNormalMessage() en rfbserver.c no sanea msg.cct.length, lo que conduce a un acceso a datos no inicializados y potencialmente sensibles o, posiblemente, a otro tipo de impacto sin especificar (por ejemplo, un desbordamiento de enteros) mediante paquetes VNC especialmente manipulados. • http://www.openwall.com/lists/oss-security/2018/02/18/1 http://www.securityfocus.com/bid/103107 https://access.redhat.com/errata/RHSA-2018:1055 https://github.com/LibVNC/libvncserver/issues/218 https://lists.debian.org/debian-lts-announce/2018/03/msg00035.html https://lists.debian.org/debian-lts-announce/2019/10/msg00042.html https://lists.debian.org/debian-lts-announce/2019/11/msg00032.html https://lists.debian.org/debian-lts-announce/2019/12/msg00028.html https://se • CWE-190: Integer Overflow or Wraparound CWE-805: Buffer Access with Incorrect Length Value •
CVE-2018-7208 – binutils: Improper bounds check in coffgen.c:coff_pointerize_aux() allows for denial of service when parsing a crafted COFF file
https://notcve.org/view.php?id=CVE-2018-7208
In the coff_pointerize_aux function in coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, an index is not validated, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted file, as demonstrated by objcopy of a COFF object. En la función coff_pointerize_aux en coffgen.c en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.30, no se valida un índice. Esto permite que atacantes remotos provoquen una denegación de servicio (fallo de segmentación) o que pueda provocar otro tipo de impacto sin especificar mediante un archivo manipulado, tal y como demuestra un objcopy de un objeto COFF. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00072.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00008.html http://www.securityfocus.com/bid/103077 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3032 https://security.gentoo.org/glsa/201811-17 https://sourceware.org/bugzilla/show_bug.cgi?id=22741 https://access.redhat.com/security/cve/CVE-2018-7208 https://bugzilla.redhat.com/show_bug.cgi?id=15 • CWE-20: Improper Input Validation •
CVE-2018-5379 – quagga: Double free vulnerability in bgpd when processing certain forms of UPDATE message allowing to crash or potentially execute arbitrary code
https://notcve.org/view.php?id=CVE-2018-5379
The Quagga BGP daemon (bgpd) prior to version 1.2.3 can double-free memory when processing certain forms of UPDATE message, containing cluster-list and/or unknown attributes. A successful attack could cause a denial of service or potentially allow an attacker to execute arbitrary code. El demonio Quagga BGP (bgpd), en versiones anteriores a la 1.2.3, puede realizar una doble liberación (double free) de memoria al procesar ciertos formularios de un mensaje UPDATE que contienen atributos cluster-list y/o desconocidos. Un ataque con éxito podría provocar una denegación de servicio (DoS) o permitir que un atacante ejecute código arbitrario.
