CVE-2018-5089 – Mozilla: Memory safety bugs fixed in Firefox 58 and Firefox ESR 52.6 (MFSA 2018-03)
https://notcve.org/view.php?id=CVE-2018-5089
Memory safety bugs were reported in Firefox 57 and Firefox ESR 52.5. 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 Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58. Se han informado de errores de seguridad de memoria en Firefox 57 y Firefox ESR 52.5. Algunos de estos errores mostraron evidencias de corrupción de memoria y se cree que, con el esfuerzo necesario, se podrían explotar para ejecutar código arbitrario. • http://www.securityfocus.com/bid/102783 http://www.securitytracker.com/id/1040270 https://access.redhat.com/errata/RHSA-2018:0122 https://access.redhat.com/errata/RHSA-2018:0262 https://bugzilla.mozilla.org/buglist.cgi?bug_id=1412420%2C1426783%2C1422389%2C1415598%2C1410134%2C1408017%2C1224396%2C1382366%2C1415582%2C1417797%2C1409951%2C1414452%2C1428589%2C1425780%2C1399520%2C1418854%2C1408276%2C1412145%2C1331209%2C1425612 https://lists.debian.org/debian-lts-announce/2018/01/msg00030.html https://lists.debian.org/debian-lts • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2018-5099 – Mozilla: Use-after-free with widget listener (MFSA 2018-03)
https://notcve.org/view.php?id=CVE-2018-5099
A use-after-free vulnerability can occur when the widget listener is holding strong references to browser objects that have previously been freed, resulting in a potentially exploitable crash when these references are used. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58. Puede ocurrir una vulnerabilidad de uso de memoria previamente liberada cuando el listener de widgets tiene referencias robustas con los objetos del navegador que se han liberado previamente, resultando en un cierre inesperado potencialmente explotable cuando se utilizan estas referencias. Esta vulnerabilidad afecta a las versiones anteriores a la 52.6 de Thunderbird, las versiones anteriores a la 52.6 de Firefox ESR y las versiones anteriores a la 58 de Firefox. • http://www.securityfocus.com/bid/102783 http://www.securitytracker.com/id/1040270 https://access.redhat.com/errata/RHSA-2018:0122 https://access.redhat.com/errata/RHSA-2018:0262 https://bugzilla.mozilla.org/show_bug.cgi?id=1416878 https://lists.debian.org/debian-lts-announce/2018/01/msg00030.html https://lists.debian.org/debian-lts-announce/2018/01/msg00036.html https://usn.ubuntu.com/3544-1 https://www.debian.org/security/2018/dsa-4096 https://www.debian.org/securi • CWE-416: Use After Free •
CVE-2017-7843 – Mozilla: Web worker in Private Browsing mode can write IndexedDB data
https://notcve.org/view.php?id=CVE-2017-7843
When Private Browsing mode is used, it is possible for a web worker to write persistent data to IndexedDB and fingerprint a user uniquely. IndexedDB should not be available in Private Browsing mode and this stored data will persist across multiple private browsing mode sessions because it is not cleared when exiting. This vulnerability affects Firefox ESR < 52.5.2 and Firefox < 57.0.1. Cuando se utiliza el modo Navegación Privada, es posible que un trabajador web escriba datos persistentes en IndexedDB y realice fingerprinting en un usuario de forma única. IndexedDB no debería estar disponible en modo Navegación Privada y estos datos almacenados persistirán en varias sesiones en modo Navegación Privada porque no se borran al cerrar. • http://www.securityfocus.com/bid/102039 http://www.securityfocus.com/bid/102112 http://www.securitytracker.com/id/1039954 https://access.redhat.com/errata/RHSA-2017:3382 https://bugzilla.mozilla.org/show_bug.cgi?id=1410106 https://lists.debian.org/debian-lts-announce/2017/12/msg00003.html https://www.debian.org/security/2017/dsa-4062 https://www.mozilla.org/security/advisories/mfsa2017-27 https://www.mozilla.org/security/advisories/mfsa2017-28 https://access.redhat.com/securit • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer •

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 •
