CVSS: 9.8EPSS: 0%CPEs: 19EXPL: 0CVE-2018-12390 – Mozilla: Memory safety bugs fixed in Firefox 63 and Firefox ESR 60.3
https://notcve.org/view.php?id=CVE-2018-12390
Mozilla developers and community members reported memory safety bugs present in Firefox 62 and Firefox ESR 60.2. 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 < 63, Firefox ESR < 60.3, and Thunderbird < 60.3. Los desarrolladores de Mozilla y los miembros de la comunidad reportaron problemas de seguridad existentes en Firefox 62 y Firefox ESR 60.2. Algunos de estos errores mostraban 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/105718 http://www.securityfocus.com/bid/105769 http://www.securitytracker.com/id/1041944 https://access.redhat.com/errata/RHSA-2018:3005 https://access.redhat.com/errata/RHSA-2018:3006 https://access.redhat.com/errata/RHSA-2018:3531 https://access.redhat.com/errata/RHSA-2018:3532 https://bugzilla.mozilla.org/buglist.cgi?bug_id=1487098%2C1487660%2C1490234%2C1496159%2C1443748%2C1496340%2C1483905%2C1493347%2C1488803%2C1498701%2C1498482%2C1442010%2C1495245%2C1483699%2C1469486%2C1 • 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') •
CVSS: 7.5EPSS: 0%CPEs: 18EXPL: 0CVE-2018-12393 – Mozilla: Integer overflow during Unicode conversion while loading JavaScript
https://notcve.org/view.php?id=CVE-2018-12393
A potential vulnerability was found in 32-bit builds where an integer overflow during the conversion of scripts to an internal UTF-16 representation could result in allocating a buffer too small for the conversion. This leads to a possible out-of-bounds write. *Note: 64-bit builds are not vulnerable to this issue.*. This vulnerability affects Firefox < 63, Firefox ESR < 60.3, and Thunderbird < 60.3. Se ha encontrado una vulnerabilidad potencial en los builds de 32 bit en la que un desbordamiento de enteros durante la conversión de scripts en una representación UTF-16 interna podría conducir a la asignación de un búfer demasiado pequeño para dicha conversión. • http://www.securityfocus.com/bid/105718 http://www.securityfocus.com/bid/105769 http://www.securitytracker.com/id/1041944 https://access.redhat.com/errata/RHSA-2018:3005 https://access.redhat.com/errata/RHSA-2018:3006 https://access.redhat.com/errata/RHSA-2018:3531 https://access.redhat.com/errata/RHSA-2018:3532 https://bugzilla.mozilla.org/show_bug.cgi?id=1495011 https://lists.debian.org/debian-lts-announce/2018/11/msg00008.html https://lists.debian.org/debian-lts-announ • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2018-12396
A vulnerability where a WebExtension can run content scripts in disallowed contexts following navigation or other events. This allows for potential privilege escalation by the WebExtension on sites where content scripts should not be run. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63. Una vulnerabilidad en la que WebExtensions pueden ejecutar scripts de contenido en contextos no permitidos tras una navegación u otros eventos. Esto permite el escalado de privilegios potencial mediante WebExtensions en sitios en los que los scripts de contenido no deberían ejecutarse. • http://www.securityfocus.com/bid/105718 http://www.securitytracker.com/id/1041944 https://access.redhat.com/errata/RHSA-2018:3005 https://access.redhat.com/errata/RHSA-2018:3006 https://bugzilla.mozilla.org/show_bug.cgi?id=1483602 https://lists.debian.org/debian-lts-announce/2018/11/msg00008.html https://security.gentoo.org/glsa/201811-04 https://usn.ubuntu.com/3801-1 https://www.debian.org/security/2018/dsa-4324 https://www.mozilla.org/security/advisories/mfsa2018-26&# • CWE-284: Improper Access Control CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 9.8EPSS: 0%CPEs: 19EXPL: 0CVE-2018-12392 – Mozilla: Crash with nested event loops
https://notcve.org/view.php?id=CVE-2018-12392
When manipulating user events in nested loops while opening a document through script, it is possible to trigger a potentially exploitable crash due to poor event handling. This vulnerability affects Firefox < 63, Firefox ESR < 60.3, and Thunderbird < 60.3. Al manipular los eventos de usuario en bucles anidados durante la apertura de un documento mediante script, es posible desencadenar un cierre inesperado potencialmente explotable debido a la mala gestión de eventos. Esta vulnerabilidad afecta a las versiones anteriores a la 63 de Firefox, las versiones anteriores a la 60.3 de Firefox ESR y las versiones anteriores a la 60.3 de Thunderbird. • http://www.securityfocus.com/bid/105718 http://www.securityfocus.com/bid/105769 http://www.securitytracker.com/id/1041944 https://access.redhat.com/errata/RHSA-2018:3005 https://access.redhat.com/errata/RHSA-2018:3006 https://access.redhat.com/errata/RHSA-2018:3531 https://access.redhat.com/errata/RHSA-2018:3532 https://bugzilla.mozilla.org/show_bug.cgi?id=1492823 https://lists.debian.org/debian-lts-announce/2018/11/msg00008.html https://lists.debian.org/debian-lts-announ • CWE-364: Signal Handler Race Condition •
CVSS: 8.1EPSS: 0%CPEs: 16EXPL: 1CVE-2018-18559 – kernel: Use-after-free due to race condition in AF_PACKET implementation
https://notcve.org/view.php?id=CVE-2018-18559
In the Linux kernel through 4.19, a use-after-free can occur due to a race condition between fanout_add from setsockopt and bind on an AF_PACKET socket. This issue exists because of the 15fe076edea787807a7cdc168df832544b58eba6 incomplete fix for a race condition. The code mishandles a certain multithreaded case involving a packet_do_bind unregister action followed by a packet_notifier register action. Later, packet_release operates on only one of the two applicable linked lists. The attacker can achieve Program Counter control. • https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2019:0163 https://access.redhat.com/errata/RHSA-2019:0188 https://access.redhat.com/errata/RHSA-2019:1170 https://access.redhat.com/errata/RHSA-2019:1190 https://access.redhat.com/errata/RHSA-2019:3967 https://access.redhat.com/errata/RHSA-2019:4159 https://access.redhat.com/errata/RHSA-2020:0174 https://blogs.securiteam.com/index.php/archives/3731 https://access.redhat.com/security/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
