CVE-2013-2234 – Kernel: net: information leak in AF_KEY notify
https://notcve.org/view.php?id=CVE-2013-2234
The (1) key_notify_sa_flush and (2) key_notify_policy_flush functions in net/key/af_key.c in the Linux kernel before 3.10 do not initialize certain structure members, which allows local users to obtain sensitive information from kernel heap memory by reading a broadcast message from the notify interface of an IPSec key_socket. Las funciones (1) key_notify_sa_flush y (2) key_notify_policy_flush en net/key/af_key.c en el kernel de linux anterior a v3.10 no inicializa ciertos miembros de la estructura, lo que permite a usuarios locales obtener información sensible de la memoria de tipo montículo del kernel leyendo un mensaje de difusión de la interfaz de notificación de un key_socket IPSec. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a5cc68f3d63306d0d288f31edfc2ae6ef8ecd887 http://lists.opensuse.org/opensuse-security-announce/2013-09/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2013-09/msg00004.html http://lists.opensuse.org/opensuse-updates/2013-12/msg00129.html http://rhn.redhat.com/errata/RHSA-2013-1166.html http://rhn.redhat.com/errata/RHSA-2013-1645.html http://www.debian.org/security/2013/dsa-2766 http://www • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2013-2206 – kernel: sctp: duplicate cookie handling NULL pointer dereference
https://notcve.org/view.php?id=CVE-2013-2206
The sctp_sf_do_5_2_4_dupcook function in net/sctp/sm_statefuns.c in the SCTP implementation in the Linux kernel before 3.8.5 does not properly handle associations during the processing of a duplicate COOKIE ECHO chunk, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted SCTP traffic. La función sctp_sf_do_5_2_4_dupcook en net/sctp/sm_statefuns.c en la implementación SCTP en el kernel de Linux anterior a v3.8.5 no maneja correctamente asociaciones durante el proceso de duplicación de COOKIE ECHO chunk, lo que permite a atacantes remotos causar una denegación de servicios (puntero NULL y caída del sistema) o posiblemente tenga otro impacto sin especificar a través de tráfico SCTP. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=f2815633504b442ca0b0605c16bf3d88a3a0fcea http://lists.opensuse.org/opensuse-security-announce/2013-11/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2013-11/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2013-11/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2013-11/msg00024.html http://lists.opensuse.org/opensuse-updates/2013-12/msg00129.html http://rhn.redhat.com • CWE-476: NULL Pointer Dereference •
CVE-2013-1943 – kernel: kvm: missing check in kvm_set_memory_region()
https://notcve.org/view.php?id=CVE-2013-1943
The KVM subsystem in the Linux kernel before 3.0 does not check whether kernel addresses are specified during allocation of memory slots for use in a guest's physical address space, which allows local users to gain privileges or obtain sensitive information from kernel memory via a crafted application, related to arch/x86/kvm/paging_tmpl.h and virt/kvm/kvm_main.c. El subsistema KVM en el kernel de Linux anterior a v3.0 no comprueba si las direcciones del núcleo se especifican durante la asignación de slots de memoria para su uso en el espacio de direcciones físicas huesped, permitiendo a usuarios locales conseguir privilegios u obtener información confidencial de la memoria del núcleo a través de una aplicación especialmente diseñada, relacionada con arch/x86/kvm/paging_tmpl.h y virt/kvm/kvm_main.c. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=fa3d315a4ce2c0891cdde262562e710d95fba19e http://web.archive.org/web/20130329070349/http://ftp.osuosl.org/pub/linux/kernel/v3.0/ChangeLog-3.0 http://www.ubuntu.com/usn/USN-1939-1 https://bugzilla.redhat.com/show_bug.cgi?id=950490 https://github.com/torvalds/linux/commit/fa3d315a4ce2c0891cdde262562e710d95fba19e https://access.redhat.com/security/cve/CVE-2013-1943 • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
