CVSS: 9.8EPSS: 1%CPEs: 14EXPL: 1CVE-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 •
CVSS: 7.8EPSS: 1%CPEs: 4EXPL: 0CVE-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 •
CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-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 •

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 •
