CVE-2017-7828 – Mozilla: Use-after-free of PressShell while restyling layout (MFSA 2017-25)
https://notcve.org/view.php?id=CVE-2017-7828
A use-after-free vulnerability can occur when flushing and resizing layout because the "PressShell" object has been freed while still in use. This results in a potentially exploitable crash during these operations. This vulnerability affects Firefox < 57, Firefox ESR < 52.5, and Thunderbird < 52.5. Puede ocurrir una vulnerabilidad de uso de memoria previamente liberada cuando se alinea y redimensiona la disposición porque el objeto "PressShell'" se ha liberado cuando se estaba utilizando. Esto resulta en un cierre inesperado potencialmente explotable durante estas operaciones. • http://www.securityfocus.com/bid/101832 http://www.securitytracker.com/id/1039803 https://access.redhat.com/errata/RHSA-2017:3247 https://access.redhat.com/errata/RHSA-2017:3372 https://bugzilla.mozilla.org/show_bug.cgi?id=1406750 https://bugzilla.mozilla.org/show_bug.cgi?id=1412252 https://lists.debian.org/debian-lts-announce/2017/11/msg00018.html https://lists.debian.org/debian-lts-announce/2017/12/msg00001.html https://www.debian.org/security/2017/dsa-4035 https:// • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2017-7830
The Resource Timing API incorrectly revealed navigations in cross-origin iframes. This is a same-origin policy violation and could allow for data theft of URLs loaded by users. This vulnerability affects Firefox < 57, Firefox ESR < 52.5, and Thunderbird < 52.5. La API Resource Timing revelaba incorrectamente las navegaciones en iframes cross-origin.

CVE-2017-7826 – Mozilla: Memory safety bugs fixed in Firefox 57 and Firefox ESR 52.5 (MFSA 2017-25)
https://notcve.org/view.php?id=CVE-2017-7826
Memory safety bugs were reported in Firefox 56 and Firefox ESR 52.4. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 57, Firefox ESR < 52.5, and Thunderbird < 52.5. Se han informado de errores de seguridad de memoria en Firefox 56 y Firefox ESR 52.4.

CVE-2017-7813
https://notcve.org/view.php?id=CVE-2017-7813
Inside the JavaScript parser, a cast of an integer to a narrower type can result in data read from outside the buffer being parsed. This usually results in a non-exploitable crash, but can leak a limited amount of information from memory if it matches JavaScript identifier syntax. This vulnerability affects Firefox < 56. Dentro del analizador JavaScript, el retorno de un entero a un tipo más estrecho puede resultar en que los datos leídos desde fuera del búfer sean analizados. Esto generalmente resulta en un cierre inesperado no explotable, pero puede filtrar una cantidad limitada de información de la memoria si coincide con la sintaxis del identificador JavaScript. • http://www.securityfocus.com/bid/101057 http://www.securitytracker.com/id/1039465 https://bugzilla.mozilla.org/show_bug.cgi?id=1383951 https://www.mozilla.org/security/advisories/mfsa2017-21 • CWE-125: Out-of-bounds Read CWE-704: Incorrect Type Conversion or Cast •
