CVSS: 7.8EPSS: 0%CPEs: 19EXPL: 1CVE-2019-7310 – poppler: heap-based buffer over-read in XRef::getEntry in XRef.cc
https://notcve.org/view.php?id=CVE-2019-7310
In Poppler 0.73.0, a heap-based buffer over-read (due to an integer signedness error in the XRef::getEntry function in XRef.cc) allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document, as demonstrated by pdftocairo. En la versión 0.73.0 de Poppler, una sobrelectura de búfer (debido a un error en la propiedad signedness de un número entero en la función XRef::getEntry function en XRef.cc) basada en memoria dinámica (heap) permite a los atacantes remotos causar una denegación de servicio (cierre inesperado de la aplicación) o, potencialmente, otro impacto no especificado mediante un documento PDF manipulado, tal y como queda demostrado con pdftocairo. • http://www.securityfocus.com/bid/106829 https://access.redhat.com/errata/RHSA-2019:2022 https://access.redhat.com/errata/RHSA-2019:2713 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=12797 https://gitlab.freedesktop.org/poppler/poppler/issues/717 https://lists.debian.org/debian-lts-announce/2019/03/msg00008.html https://lists.debian.org/debian-lts-announce/2020/11/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BI7NLDN2 • CWE-125: Out-of-bounds Read CWE-681: Incorrect Conversion between Numeric Types •
CVSS: 5.6EPSS: 0%CPEs: 7EXPL: 0CVE-2019-7308 – Linux Insufficient eBPF Spectre V1 Mitigation
https://notcve.org/view.php?id=CVE-2019-7308
kernel/bpf/verifier.c in the Linux kernel before 4.20.6 performs undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize, leading to side-channel attacks. En el kernel de Linux, en versiones anteriores a la 4.20.6, "kernel/bpf/verifier.c" realiza especulaciones fuera de límites no deseables en la aritmética de punteros en varias ocasiones, incluyendo casos de diferentes ramas con distintos estados o límites que hay que sanear, conduciendo a ataques de canal lateral. It has been discovered that the Linux eBPF Spectre v1 mitigation is insufficient. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=979d63d50c0c0f7bc537bf821e056cc9fe5abd38 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d3bd7413e0ca40b60cf60d4003246d067cafdeda http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00052.html http://www.securityfocus.com/bid/106827 https://bugs.chromium.org/p/project-zero/issues/detail?id=1711 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.20.6 https://github.com/torvalds/ • CWE-189: Numeric Errors •

A crash and out-of-bounds read can occur when the buffer of a texture client is freed while it is still in use during graphic operations. This results is a potentially exploitable crash and the possibility of reading from the memory of the freed buffers. This vulnerability affects Firefox < 65. Un cierre inesperado y una lectura fuera de límites podrían ocurrir cuando el búfer de la textura de un cliente se libera mientras está en uso durante las operaciones gráficas. Esto resulta en un cierre potencialmente explotable y la posibilidad de leer desde la memoria de los búferes liberados. • http://www.securityfocus.com/bid/106773 https://usn.ubuntu.com/3874-1 https://www.mozilla.org/security/advisories/mfsa2019-01 • CWE-125: Out-of-bounds Read •
CVSS: 6.1EPSS: 0%CPEs: 29EXPL: 0CVE-2018-18506 – Mozilla: Proxy Auto-Configuration file can define localhost access to be proxied
https://notcve.org/view.php?id=CVE-2018-18506
When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attacks on services and tools that bind to the localhost for networked behavior if they are accessed through browsing. This vulnerability affects Firefox < 65. Cuando la autodetección del proxy está habilitada, si un servidor web proporciona un archivo de autoconfiguración de proxy (PAC) o si dicho archivo se carga localmente, este último puede especificar peticiones al host local que están destinadas a enviarse a través del proxy hacia otro servidor. Este comportamiento está prohibido por defecto cuando un proxy se configura manualmente. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00043.html http://www.securityfocus.com/bid/106773 https://access.redhat.com/errata/RHSA-2019:0622 https://access.redhat.com/errata/RHSA-2019:0623 https://access.redhat.com/errata/RHSA-2019:0680 https:/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

When loading a document with Apache Open Office 4.1.5 and earlier with smaller end line termination than the operating system uses, the defect occurs. In this case OpenOffice runs into an Arithmetic Overflow at a string length calculation. Al cargar un documento con Apache Open Office, en versiones 4.1.5 y anteriores, con una terminación de final de línea más pequeña que las que emplea el sistema operativo, ocurre este defecto.
