CVE-2018-6927 – kernel: Integer overflow in futex.c:futux_requeue can lead to denial of service or unspecified impact
https://notcve.org/view.php?id=CVE-2018-6927
The futex_requeue function in kernel/futex.c in the Linux kernel before 4.14.15 might allow attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a negative wake or requeue value. La función futex_requeue en kernel/futex.c en el kernel de Linux, en versiones anteriores a la 4.14.15, podría permitir que atacantes provoquen una denegación de servicio (desbordamiento de enteros) o que puedan causar otro tipo de impacto sin especificar desencadenando un valor wake o requeue negativo. The futex_requeue function in kernel/futex.c in the Linux kernel, before 4.14.15, might allow attackers to cause a denial of service (integer overflow) or possibly have unspecified other impacts by triggering a negative wake or requeue value. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=fbe0e839d1e22d88810f3ee3e2f1479be4c0aa4a http://www.securityfocus.com/bid/103023 https://access.redhat.com/errata/RHSA-2018:0654 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://github.com/torvalds/linux/commit/fbe0e839d1e22d88810f3ee3e2f1479be4c0aa4a https://lists.debian.org/debian-lts-announce/2018/05/msg00000.html https://usn.ubuntu.com/3619-1 https://usn.ubuntu. • CWE-190: Integer Overflow or Wraparound •
CVE-2018-6871 – LibreOffice < 6.0.1 - '=WEBSERVICE' Remote Arbitrary File Disclosure
https://notcve.org/view.php?id=CVE-2018-6871
LibreOffice before 5.4.5 and 6.x before 6.0.1 allows remote attackers to read arbitrary files via =WEBSERVICE calls in a document, which use the COM.MICROSOFT.WEBSERVICE function. LibreOffice, en versiones anteriores a la 5.4.5 y versiones 6.x anteriores a la 6.0.1, permite que atacantes remotos lean archivos arbitrarios mediante llamadas =WEBSERVICE en un documento, que emplea la función COM.MICROSOFT.WEBSERVICE. A flaw was found in libreoffice before 5.4.5 and before 6.0.1. Arbitrary remote file disclosure may be achieved by the use of the WEBSERVICE formula in a specially crafted ODS file. LibreOffice suffers from a remote arbitrary file disclosure vulnerability. • https://www.exploit-db.com/exploits/44022 https://access.redhat.com/errata/RHSA-2018:0418 https://access.redhat.com/errata/RHSA-2018:0517 https://cgit.freedesktop.org/libreoffice/core/commit/?h=libreoffice-5-4-5&id=a916fc0c0e0e8b10cb4158fa0fa173fe205d434a https://github.com/jollheef/libreoffice-remote-arbitrary-file-disclosure https://usn.ubuntu.com/3579-1 https://www.debian.org/security/2018/dsa-4111 https://www.libreoffice.org/about-us/security/advisories/cve-2018-1055 https://access.red • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2018-6560 – flatpak: sandbox escape in D-Bus filtering by a crafted authentication handshake
https://notcve.org/view.php?id=CVE-2018-6560
In dbus-proxy/flatpak-proxy.c in Flatpak before 0.8.9, and 0.9.x and 0.10.x before 0.10.3, crafted D-Bus messages to the host can be used to break out of the sandbox, because whitespace handling in the proxy is not identical to whitespace handling in the daemon. En dbus-proxy/flatpak-proxy.c en Flatpak en versiones anteriores a la 0.8.9, 0.9.x y 0.10.x anteriores a la 0.10.3, se pueden utilizar mensajes D-Bus manipulados para salir del sandbox, ya que la gestión de los espacios en blanco en el proxy no es idéntica a cómo gestiona el demonio los espacios en blanco. It was found that flatpak's D-Bus proxy did not properly filter the access to D-Bus during the authentication protocol. A specially crafted flatpak application could use this flaw to bypass all restrictions imposed by flatpak and have full access to the D-BUS interface. • https://access.redhat.com/errata/RHSA-2018:2766 https://github.com/flatpak/flatpak/commit/52346bf187b5a7f1c0fe9075b328b7ad6abe78f6 https://github.com/flatpak/flatpak/releases/tag/0.10.3 https://github.com/flatpak/flatpak/releases/tag/0.8.9 https://access.redhat.com/security/cve/CVE-2018-6560 https://bugzilla.redhat.com/show_bug.cgi?id=1542207 • CWE-270: Privilege Context Switching Error CWE-436: Interpretation Conflict •
CVE-2018-1049 – systemd: automount: access to automounted volumes can lock up
https://notcve.org/view.php?id=CVE-2018-1049
In systemd prior to 234 a race condition exists between .mount and .automount units such that automount requests from kernel may not be serviced by systemd resulting in kernel holding the mountpoint and any processes that try to use said mount will hang. A race condition like this may lead to denial of service, until mount points are unmounted. En systemd en versiones anteriores a la 234, existe una condición de carrera entre las unidades .mount y .automount, de forma que las peticiones automount del kernel podrían no ser ofrecidas por systemd. Esto resulta en que el kernel retiene el mountpoint y cualquier proceso que intente emplear este mount se bloqueará. Una condición de carrera como esta podría conducir a una denegación de servicio (DoS) hasta que los puntos de montaje se desmonten. • http://www.securitytracker.com/id/1041520 https://access.redhat.com/errata/RHSA-2018:0260 https://bugzilla.redhat.com/show_bug.cgi?id=1534701 https://lists.debian.org/debian-lts-announce/2018/11/msg00017.html https://usn.ubuntu.com/3558-1 https://access.redhat.com/security/cve/CVE-2018-1049 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2018-5802 – LibRaw: Out-of-bounds read in kodak_radc_load_raw function internal/dcraw_common.cpp
https://notcve.org/view.php?id=CVE-2018-5802
An error within the "kodak_radc_load_raw()" function (internal/dcraw_common.cpp) related to the "buf" variable in LibRaw versions prior to 0.18.7 can be exploited to cause an out-of-bounds read memory access and subsequently cause a crash. Un error en la función "kodak_radc_load_raw()" (internal/dcraw_common.cpp) relacionada con la variable "buf" en LibRaw en versiones anteriores a la 0.18.7 se puede explotar para provocar un acceso de lectura a la memoria fuera de límites y un cierre inesperado. An out-of-bounds read flaw was found in the way LibRaw processed images. An attacker could potentially use this flaw to crash applications using LibRaw by tricking them into processing crafted images. • https://access.redhat.com/errata/RHSA-2018:3065 https://github.com/LibRaw/LibRaw/blob/master/Changelog.txt https://github.com/LibRaw/LibRaw/commit/8682ad204392b914ab1cc6ebcca9c27c19c1a4b4 https://lists.debian.org/debian-lts-announce/2019/03/msg00036.html https://secuniaresearch.flexerasoftware.com/advisories/79000 https://secuniaresearch.flexerasoftware.com/secunia_research/2018-1 https://usn.ubuntu.com/3615-1 https://access.redhat.com/security/cve/CVE-2018-5802 https://bugzilla.redhat.com/show_bug.cg • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read •
