CVSS: 5.3EPSS: 0%CPEs: 22EXPL: 1CVE-2017-7791 – Mozilla: Spoofing following page navigation with data: protocol and modal alerts (MFSA 2017-19)
https://notcve.org/view.php?id=CVE-2017-7791
On pages containing an iframe, the "data:" protocol can be used to create a modal alert that will render over arbitrary domains following page navigation, spoofing of the origin of the modal alert from the iframe content. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55. En las páginas que contienen un iframe, el protocolo "data:" se puede emplear para crear una alerta modal que se representará sobre dominios arbitrarios siguiendo la navegación, suplantando el origen de la alerta modal del contenido iframe. La vulnerabilidad afecta a Thunderbird en versiones anteriores a la 52.3, Firefox ESR en versiones anteriores a la 52.3 y Firefox en versiones anteriores a la 55. • http://www.securityfocus.com/bid/100240 http://www.securitytracker.com/id/1039124 https://access.redhat.com/errata/RHSA-2017:2456 https://access.redhat.com/errata/RHSA-2017:2534 https://bugzilla.mozilla.org/show_bug.cgi?id=1365875 https://security.gentoo.org/glsa/201803-14 https://www.debian.org/security/2017/dsa-3928 https://www.debian.org/security/2017/dsa-3968 https://www.mozilla.org/security/advisories/mfsa2017-18 https://www.mozilla.org/security/advisories/mfsa2017-19 • CWE-20: Improper Input Validation CWE-829: Inclusion of Functionality from Untrusted Control Sphere •

https://notcve.org/view.php?id=CVE-2017-7784
A use-after-free vulnerability can occur when reading an image observer during frame reconstruction after the observer has been freed. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55. Puede ocurrir una vulnerabilidad de uso de memoria previamente liberada al leer un observador de imagen durante la reconstrucción de frames una vez se ha liberado el observador. Esto resulta en un cierre inesperado potencialmente explotable. • http://www.securityfocus.com/bid/100202 http://www.securitytracker.com/id/1039124 https://access.redhat.com/errata/RHSA-2017:2456 https://access.redhat.com/errata/RHSA-2017:2534 https://bugzilla.mozilla.org/show_bug.cgi?id=1376087 https://security.gentoo.org/glsa/201803-14 https://www.debian.org/security/2017/dsa-3928 https://www.debian.org/security/2017/dsa-3968 https://www.mozilla.org/security/advisories/mfsa2017-18 https://www.mozilla.org/security/advisories/mfsa2017-19 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2017-7786
A buffer overflow can occur when the image renderer attempts to paint non-displayable SVG elements. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55. Puede ocurrir un desbordamiento de búfer cuando el renderizador de imagen intenta pintar elementos SVG no mostrables.

https://notcve.org/view.php?id=CVE-2017-7980
Heap-based buffer overflow in Cirrus CLGD 54xx VGA Emulator in Quick Emulator (Qemu) 2.8 and earlier allows local guest OS users to execute arbitrary code or cause a denial of service (crash) via vectors related to a VNC client updating its display after a VGA operation. Desbordamiento de búfer basado en memoria dinámica (heap) en Cirrus CLGD 54xx VGA Emulator en Quick Emulator (Qemu) en versiones 2.8 y anteriores permite que los usuarios invitados del sistema operativo ejecuten código arbitrario o provoquen una denegación de servicio (DoS) mediante vectores relacionados con un cliente VNC que actualiza su display después de una operación VGA. An out-of-bounds r/w access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data via various bitblt functions. A privileged user inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. • http://ubuntu.com/usn/usn-3289-1 http://www.openwall.com/lists/oss-security/2017/04/21/1 http://www.securityfocus.com/bid/102129 http://www.securityfocus.com/bid/97955 https://access.redhat.com/errata/RHSA-2017:0980 https://access.redhat.com/errata/RHSA-2017:0981 https://access.redhat.com/errata/RHSA-2017:0982 https://access.redhat.com/errata/RHSA-2017:0983 https://access.redhat.com/errata/RHSA-2017:0984 https://access.redhat.com/errata/RHSA-2017:0988 https • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2016-9603
A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. Se ha detectado una vulnerabilidad de desbordamiento de búfer basado en memoria dinámica (heap) en el soporte del controlador de pantalla VNC del emulador Cirrus CLGD 54xx VGA de QEMU en versiones anteriores a la 2.9. El problema podía ocurrir cuando un cliente VNC intentaba actualizar su pantalla después de que un invitado realizara una operación VGA. Un usuario/proceso privilegiado dentro de un guest podría usar esta vulnerabilidad para provocar que el proceso de QEMU se cierre inesperadamente o, potencialmente, ejecutar código arbitrario en el host con privilegios del proceso de QEMU. • http://www.securityfocus.com/bid/96893 http://www.securitytracker.com/id/1038023 https://access.redhat.com/errata/RHSA-2017:0980 https://access.redhat.com/errata/RHSA-2017:0981 https://access.redhat.com/errata/RHSA-2017:0982 https://access.redhat.com/errata/RHSA-2017:0983 https://access.redhat.com/errata/RHSA-2017:0984 https://access.redhat.com/errata/RHSA-2017:0985 https://access.redhat.com/errata/RHSA-2017:0987 https://access.redhat.com/errata/RHSA-2017:0988 https:& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
