CVSS: 9.8EPSS: 0%CPEs: 21EXPL: 0CVE-2017-5402 – Mozilla: Use-after-free working with events in FontFace objects (MFSA 2017-06)
https://notcve.org/view.php?id=CVE-2017-5402
A use-after-free can occur when events are fired for a "FontFace" object after the object has been already been destroyed while working with fonts. This results in a potentially exploitable crash. This vulnerability affects Firefox < 52, Firefox ESR < 45.8, Thunderbird < 52, and Thunderbird < 45.8. Puede ocurrir un uso de memoria previamente liberada cuando se lanzan eventos para un objeto "FontFace" una vez el objeto ha sido ya destruido mientras se trabaja con fuentes. Esto resulta en un cierre inesperado potencialmente explotable. • http://rhn.redhat.com/errata/RHSA-2017-0459.html http://rhn.redhat.com/errata/RHSA-2017-0461.html http://rhn.redhat.com/errata/RHSA-2017-0498.html http://www.securityfocus.com/bid/96664 http://www.securitytracker.com/id/1037966 https://bugzilla.mozilla.org/show_bug.cgi?id=1334876 https://security.gentoo.org/glsa/201705-06 https://security.gentoo.org/glsa/201705-07 https://www.debian.org/security/2017/dsa-3805 https://www.debian.org/security/2017/dsa-3832 https • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2017-5407
Using SVG filters that don't use the fixed point math implementation on a target iframe, a malicious page can extract pixel values from a targeted user. This can be used to extract history information and read text values across domains. This violates same-origin policy and leads to information disclosure. This vulnerability affects Firefox < 52, Firefox ESR < 45.8, Thunderbird < 52, and Thunderbird < 45.8. Mediante el uso de filtros SVG que no emplean la implementación de matemática de punto fijo en un iframe objetivo, una página maliciosa puede extraer valores de píxeles de un usuario objetivo. • http://rhn.redhat.com/errata/RHSA-2017-0459.html http://rhn.redhat.com/errata/RHSA-2017-0461.html http://rhn.redhat.com/errata/RHSA-2017-0498.html http://www.securityfocus.com/bid/96693 http://www.securitytracker.com/id/1037966 https://bugzilla.mozilla.org/show_bug.cgi?id=1336622 https://security.gentoo.org/glsa/201705-06 https://security.gentoo.org/glsa/201705-07 https://www.debian.org/security/2017/dsa-3805 https://www.debian.org/security/2017/dsa-3832 https • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

On Linux, if the secure computing mode BPF (seccomp-bpf) filter is running when the Gecko Media Plugin sandbox is started, the sandbox fails to be applied and items that would run within the sandbox are run protected only by the running filter which is typically weak compared to the sandbox. Note: this issue only affects Linux. Other operating systems are not affected. This vulnerability affects Firefox < 52 and Thunderbird < 52. En Linux, si el filtro BPF en modo secure computing (seccomp-bpf) se está ejecutando cuando se inicia el sandbox Gecko Media Plugin, el sandbox no se puede aplicar y los ítems que se ejecutarían en el sandbox estarían protegidos solo por el filtro en ejecución, el cual suele ser débil en comparación con el sandbox. • http://www.securityfocus.com/bid/96694 http://www.securitytracker.com/id/1037966 https://bugzilla.mozilla.org/show_bug.cgi?id=1257361 https://www.mozilla.org/security/advisories/mfsa2017-05 https://www.mozilla.org/security/advisories/mfsa2017-09 • CWE-732: Incorrect Permission Assignment for Critical Resource •

https://notcve.org/view.php?id=CVE-2017-5400
JIT-spray targeting asm.js combined with a heap spray allows for a bypass of ASLR and DEP protections leading to potential memory corruption attacks. This vulnerability affects Firefox < 52, Firefox ESR < 45.8, Thunderbird < 52, and Thunderbird < 45.8. Un spray JIT que apunta a asm.js combinado con un heap spray permite la omisión de las protecciones ASLR y DEP, lo que conduce a ataques de corrupción de memoria. La vulnerabilidad afecta a Firefox en versiones anteriores a la 52, Firefox ESR en versiones anteriores a la 45.8, Thunderbird en versiones anteriores a la 52 y Thunderbird en versiones anteriores a la 45.8. • http://rhn.redhat.com/errata/RHSA-2017-0459.html http://rhn.redhat.com/errata/RHSA-2017-0461.html http://rhn.redhat.com/errata/RHSA-2017-0498.html http://www.securityfocus.com/bid/96654 http://www.securitytracker.com/id/1037966 https://bugzilla.mozilla.org/show_bug.cgi?id=1334933 https://security.gentoo.org/glsa/201705-06 https://security.gentoo.org/glsa/201705-07 https://www.debian.org/security/2017/dsa-3805 https://www.debian.org/security/2017/dsa-3832 https • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
