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. En este caso, OpenOffice sufre un desbordamiento de aritmética en un cálculo de longitud de cadena. • http://www.securityfocus.com/bid/106803 https://lists.apache.org/thread.html/7394e6b5f78a878bd0c44e9bc9adf90b8cdf49e9adc0f287145aba9b%40%3Ccommits.openoffice.apache.org%3E https://usn.ubuntu.com/3883-1 https://www.openoffice.org/security/cves/CVE-2018-11790.html • CWE-682: Incorrect Calculation •
CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2017-18360 – kernel: Division by zero in change_port_settings in drivers/usb/serial/io_ti.c resulting in a denial of service
https://notcve.org/view.php?id=CVE-2017-18360
In change_port_settings in drivers/usb/serial/io_ti.c in the Linux kernel before 4.11.3, local users could cause a denial of service by division-by-zero in the serial device layer by trying to set very high baud rates. En change_port_settings en drivers/usb/serial/io_ti.c en el kernel de Linux, en versiones anteriores a la 4.11.3, los usuarios locales podrían provocar una denegación de servicio (DoS) por medio de una división entre cero en la capa del dispositivo en serie intentando establecer tasas de baudio muy altas. A division-by-zero in set_termios(), when debugging is enabled, was found in the Linux kernel. When the [io_ti] driver is loaded, a local unprivileged attacker can request incorrect high transfer speed in the change_port_settings() in the drivers/usb/serial/io_ti.c so that the divisor value becomes zero and causes a system crash resulting in a denial of service. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6aeb75e6adfaed16e58780309613a578fe1ee90b http://www.securityfocus.com/bid/106802 https://bugzilla.suse.com/show_bug.cgi?id=1123706 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.11.3 https://github.com/torvalds/linux/commit/6aeb75e6adfaed16e58780309613a578fe1ee90b https://usn.ubuntu.com/3933-1 https://usn.ubuntu.com/3933-2 https://access.redhat.com/security/cve/CVE-2017-18360 https://bugzilla.redhat.co • CWE-369: Divide By Zero •
