https://notcve.org/view.php?id=CVE-2020-12419
When processing callbacks that occurred during window flushing in the parent process, the associated window may die; causing a use-after-free condition. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0. Al procesar devoluciones de llamada que ocurrieron durante el vaciado de la ventana en el proceso principal, la ventana asociada puede terminar; causando una condición de uso de la memoria previamente liberada. Esto podría haber conllevado a una corrupción de la memoria y un bloqueo potencialmente explotable. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00049.html https://bugzilla.mozilla.org/show_bug.cgi?id=1643874 https://security.gentoo.org/glsa/202007-09 https://security.gentoo.org/glsa/202007-10 https://usn.ubuntu.com/4421-1 https://www.mozilla. • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2020-12420
When trying to connect to a STUN server, a race condition could have caused a use-after-free of a pointer, leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0. Al intentar conectarse a un servidor STUN, una condición de carrera podría haber causado un uso de la memoria previamente liberada de un puntero, conllevando a una corrupción de la memoria y un bloqueo potencialmente explotable. Esta vulnerabilidad afecta a Firefox ESR versiones anteriores a 68.10, Firefox versiones anteriores a 78 y Thunderbird versiones anteriores a 68.10.0 The Mozilla Foundation Security Advisory describes this flaw as: When trying to connect to a STUN server, a race condition could have caused a use-after-free of a pointer, leading to memory corruption and a potentially exploitable crash. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00049.html https://bugzilla.mozilla.org/show_bug.cgi?id=1643437 https://security.gentoo.org/glsa/202007-09 https://security.gentoo.org/glsa/202007-10 https://usn.ubuntu.com/4421-1 https://www.mozilla. • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2020-12421
When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date silently without notification to the user. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0. Cuando se llevan a cabo actualizaciones de add-on, las cadenas de certificados que terminan en non-built-in-roots fueron rechazadas (incluso si fueron agregadas legítimamente por un administrador). Esto podría haber causado que los add-ons se desactualicen silenciosamente sin notificación al usuario. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00049.html https://bugzilla.mozilla.org/show_bug.cgi?id=1308251 https://security.gentoo.org/glsa/202007-09 https://security.gentoo.org/glsa/202007-10 https://usn.ubuntu.com/4421-1 https://www.mozilla. • CWE-295: Improper Certificate Validation CWE-296: Improper Following of a Certificate's Chain of Trust •
CVSS: 9.8EPSS: 0%CPEs: 21EXPL: 0CVE-2017-18922 – libvncserver: websocket decoding buffer overflow
https://notcve.org/view.php?id=CVE-2017-18922
It was discovered that websockets.c in LibVNCServer prior to 0.9.12 did not properly decode certain WebSocket frames. A malicious attacker could exploit this by sending specially crafted WebSocket frames to a server, causing a heap-based buffer overflow. Se detectó que el archivo websockets.c en LibVNCServer versiones anteriores a 0.9.12, no decodificaba apropiadamente determinados tramas de WebSocket. Un atacante malicioso podría explotar esto mediante el envío de tramas de WebSocket especialmente diseñadas hacia un servidor, causando un desbordamiento del búfer en la región heap de la memoria A flaw was found in libvncserver. A heap-based buffer overflow within the websocket decoding functionality is possible, which can lead to exploitation by a malicious attacker to overwrite a function pointer. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00066.html http://www.openwall.com/lists/oss-security/2020/06/30/3 https://bugzilla.redhat.com/show_bug.cgi?id=1852356 https://cer • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
