CVE-2015-8551
https://notcve.org/view.php?id=CVE-2015-8551
The PCI backend driver in Xen, when running on an x86 system and using Linux 3.1.x through 4.3.x as the driver domain, allows local guest administrators to hit BUG conditions and cause a denial of service (NULL pointer dereference and host OS crash) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and a crafted sequence of XEN_PCI_OP_* operations, aka "Linux pciback missing sanity checks." El controlador backend PCI en Xen, cuando se ejecuta en un sistema x86 y utiliza Linux 3.1.x hasta la versión 4.3.x como dominio de controlador, permite a administradores locales invitados alcanzar condiciones de BUG y provocar una denegación de servicio (referencia a puntero NULL y caída de SO anfitrión) aprovechando un sistema con acceso a un dispositivo físico PCI capaz de pasar a través de MSI o MSI-X y una secuencia de operaciones XEN_PCI_OP_* manipulada, también conocido como "Linux pciback missing sanity checks". • http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00094.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-08 • CWE-476: NULL Pointer Dereference •
CVE-2015-0272 – NetworkManager: remote DoS using IPv6 RA with bogus MTU
https://notcve.org/view.php?id=CVE-2015-0272
GNOME NetworkManager allows remote attackers to cause a denial of service (IPv6 traffic disruption) via a crafted MTU value in an IPv6 Router Advertisement (RA) message, a different vulnerability than CVE-2015-8215. NOME NetworkManager permite a atacantes remotos causar una denegación de servicio (interrupción del tráfico IPv6) a través de un valor MTU manipulado en un mensaje Router Advertisement (RA) IPv6, una vulnerabilidad diferente a CVE-2015-8215. It was discovered that NetworkManager would set device MTUs based on MTU values received in IPv6 RAs (Router Advertisements), without sanity checking the MTU value first. A remote attacker could exploit this flaw to create a denial of service attack, by sending a specially crafted IPv6 RA packet to disturb IPv6 communication. • http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=d5fc88e573fa58b93034b04d35a2454f5d28cad9 http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00031.html http://lists.opensuse.org/opensuse-security • CWE-20: Improper Input Validation •
CVE-2014-8160 – kernel: iptables restriction bypass if a protocol handler kernel module not loaded
https://notcve.org/view.php?id=CVE-2014-8160
net/netfilter/nf_conntrack_proto_generic.c in the Linux kernel before 3.18 generates incorrect conntrack entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols, which allows remote attackers to bypass intended access restrictions via packets with disallowed port numbers. net/netfilter/nf_conntrack_proto_generic.c en el kernel de Linux anterior a 3.18 genera entradas conntrack incorrectas durante el manejo de ciertos juegos de reglas iptables para los protocolos SCTP, DCCP, GRE, y UDP-Lite, lo que permite a atacantes remotos evadir las restricciones de acceso a través de paquetes con números de puertos rechazados. A flaw was found in the way the Linux kernel's netfilter subsystem handled generic protocol tracking. As demonstrated in the Stream Control Transmission Protocol (SCTP) case, a remote attacker could use this flaw to bypass intended iptables rule restrictions when the associated connection tracking module was not loaded on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=db29a9508a9246e77087c5531e45b2c88ec6988b http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://rhn.redhat.com/errata/RHSA-2015-0284.html http://rhn.redhat.com/errata/RHSA • CWE-20: Improper Input Validation •
CVE-2014-9584 – kernel: isofs: unchecked printing of ER records
https://notcve.org/view.php?id=CVE-2014-9584
The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel before 3.18.2 does not validate a length value in the Extensions Reference (ER) System Use Field, which allows local users to obtain sensitive information from kernel memory via a crafted iso9660 image. La función parse_rock_ridge_inode_internal en fs/isofs/rock.c en el kernel de Linux anterior a 3.18.2 no valida un valor de longitud en el campo Extensions Reference (ER) System Use, lo que permite a usuarios locales obtener información sensible de la memoria del kernel a través de una imagen iso9660 manipulada. An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=4e2024624e678f0ebb916e6192bd23c1f9fdf696 http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://lists.o • CWE-20: Improper Input Validation •
CVE-2014-9585 – kernel: ASLR bruteforce possible for vdso library
https://notcve.org/view.php?id=CVE-2014-9585
The vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel through 3.18.2 does not properly choose memory locations for the vDSO area, which makes it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD. La función vdso_addr en arch/x86/vdso/vma.c en el kernel de Linux hasta 3.18.2 no elige correctamente localizaciones de memoria para la área vDSO, lo que facilita a usuarios locales evadir el mecanismo de protección ASLR mediante la adivinación de una localización al final de un PMD. An information leak flaw was found in the way the Linux kernel's Virtual Dynamic Shared Object (vDSO) implementation performed address randomization. A local, unprivileged user could use this flaw to leak kernel memory addresses to user-space. • http://git.kernel.org/?p=linux/kernel/git/luto/linux.git%3Ba=commit%3Bh=bc3b94c31d65e761ddfe150d02932c65971b74e2 http://git.kernel.org/?p=linux/kernel/git/tip/tip.git%3Ba=commit%3Bh=fbe1bf140671619508dfa575d74a185ae53c5dbb http://lists.fedoraproject.org/pipermail/package-announce/2015-January/148480.html http://lists.opensuse.org/opensuse-security-announce/2015-01/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg0 •
