CVSS: 8.8EPSS: 1%CPEs: 4EXPL: 1CVE-2019-11764 – Mozilla: Memory safety bugs fixed in Firefox 70 and Firefox ESR 68.2
https://notcve.org/view.php?id=CVE-2019-11764
Mozilla developers and community members reported memory safety bugs present in Firefox 69 and Firefox ESR 68.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. Los desarrolladores de Mozilla y los miembros de la comunidad reportaron bugs de seguridad de memoria presentes en Firefox versión 69 y Firefox ESR versión 68.1. Algunos de estos errores mostraron evidencia de corrupción de memoria y suponemos que con un esfuerzo suficiente algunos de estos podrían ser explotados para ejecutar código arbitrario. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1558522%2C1577061%2C1548044%2C1571223%2C1573048%2C1578933%2C1575217%2C1583684%2C1586845%2C1581950%2C1583463%2C1586599 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2019-33 https://www.mozilla.org/security/advisories/mfsa2019-34 https://www.mozilla.org/security/advisories/mfsa2019-35 https://access.redhat.com/security/cve/CVE-2019-11764 https://bugzilla.redhat.com/show_bug.cgi?id=17 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 0%CPEs: 4EXPL: 0CVE-2019-11760 – Mozilla: Stack buffer overflow in WebRTC networking
https://notcve.org/view.php?id=CVE-2019-11760
A fixed-size stack buffer could overflow in nrappkit when doing WebRTC signaling. This resulted in a potentially exploitable crash in some instances. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. Un búfer de pila de tamaño fijo podría desbordarse en nrappkit cuando realiza la señalización de WebRTC. Esto resultó en un bloqueo explotable potencialmente en algunos casos. • https://bugzilla.mozilla.org/show_bug.cgi?id=1577719 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2019-33 https://www.mozilla.org/security/advisories/mfsa2019-34 https://www.mozilla.org/security/advisories/mfsa2019-35 https://access.redhat.com/security/cve/CVE-2019-11760 https://bugzilla.redhat.com/show_bug.cgi?id=1764441 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 1%CPEs: 4EXPL: 0CVE-2019-11759 – Mozilla: Stack buffer overflow in HKDF output
https://notcve.org/view.php?id=CVE-2019-11759
An attacker could have caused 4 bytes of HMAC output to be written past the end of a buffer stored on the stack. This could be used by an attacker to execute arbitrary code or more likely lead to a crash. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. Un atacante podría haber causado que 4 bytes de salida HMAC se escribieran más allá del final de un búfer almacenado en la pila. Esto podría ser usado por un atacante para ejecutar código arbitrario o, más probablemente, conllevar a un bloqueo. • https://bugzilla.mozilla.org/show_bug.cgi?id=1577953 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2019-33 https://www.mozilla.org/security/advisories/mfsa2019-34 https://www.mozilla.org/security/advisories/mfsa2019-35 https://access.redhat.com/security/cve/CVE-2019-11759 https://bugzilla.redhat.com/show_bug.cgi?id=1764440 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2019-11755
A crafted S/MIME message consisting of an inner encryption layer and an outer SignedData layer was shown as having a valid digital signature, although the signer might have had no access to the contents of the encrypted message, and might have stripped a different signature from the encrypted message. Previous versions had only suppressed showing a digital signature for messages with an outer multipart/signed layer. This vulnerability affects Thunderbird < 68.1.1. Un mensaje S/MIME diseñado que consta de una capa de cifrado interna y una capa SignedData externa se mostró con firma digital válida, aunque el firmante podría no haber tenido acceso al contenido del mensaje cifrado y podría haber eliminado una firma diferente del mensaje cifrado. Las versiones anteriores solo habían suprimido el despliegue de una firma digital para mensajes con una capa externa multiparte y firmada. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html https://bugzilla.mozilla.org/show_bug.cgi?id=1240290 https://lists.debian.org/debian-lts-announce/2019/11/msg00017.html https://seclists.org/bugtraq/2019/Nov/24 https://usn.ubuntu.com/4202-1 https://usn.ubuntu.com/4335-1 https://www.debian.org/security/2019/dsa-4571 https://www.mozilla.org/security/advisories/mfsa2019-32 • CWE-347: Improper Verification of Cryptographic Signature •

https://notcve.org/view.php?id=CVE-2019-11739
Encrypted S/MIME parts in a crafted multipart/alternative message can leak plaintext when included in a a HTML reply/forward. This vulnerability affects Thunderbird < 68.1 and Thunderbird < 60.9. Las partes S/ MIME cifradas en un mensaje multiparte y alternativo diseñado pueden perder texto plano cuando son incluidos en una respuesta y reenvío HTML. Esta vulnerabilidad afecta a Thunderbird versiones anteriores a 68.1 y Thunderbird versiones anteriores a 60.9. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html https://bugzilla.mozilla.org/show_bug.cgi?id=1571481 https://usn.ubuntu.com/4150-1 https://www.mozilla.org/security/advisories/mfsa2019-29 https://www.mozilla.org/security/advisories/mfsa2019-30 https://access.redhat.com/security/cve/CVE-2019-11739 https://bugzilla.redhat.com/show_bug.cgi?id=1752307 • CWE-319: Cleartext Transmission of Sensitive Information CWE-356: Product UI does not Warn User of Unsafe Actions •
