CVSS: 6.1EPSS: 1%CPEs: 3EXPL: 0CVE-2020-6798 – Mozilla: Incorrect parsing of template tag could result in JavaScript injection
https://notcve.org/view.php?id=CVE-2020-6798
If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer a cross-site scripting vulnerability as a result. In general, this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but is potentially a risk in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5. Si se usó una etiqueta template en una etiqueta select, el analizador podría ser confundido y permitir el análisis y la ejecución de JavaScript cuando no debería ser permitido. • https://bugzilla.mozilla.org/show_bug.cgi?id=1602944 https://security.gentoo.org/glsa/202003-02 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4278-2 https://usn.ubuntu.com/4328-1 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2020-05 https://www.mozilla.org/security/advisories/mfsa2020-06 https://www.mozilla.org/security/advisories/mfsa2020-07 https://access.redhat.com/security/cve/CVE-2020-6798 https://bugzilla. • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

https://notcve.org/view.php?id=CVE-2020-6800
Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firefox ESR 68.4. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5.

Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type confusion. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Firefox ESR < 68.4.1, Thunderbird < 68.4.1, and Firefox < 72.0.1.

https://notcve.org/view.php?id=CVE-2019-17005
The plain text serializer used a fixed-size array for the number of <ol> elements it could process; however it was possible to overflow the static-sized array leading to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. El serializador de texto plano utilizó una matriz de tamaño fijo para el número de elementos (ol) que podía procesar; sin embargo, fue posible desbordar la matriz de tamaño estático conllevando a un corrupción de la memoria y un bloqueo explotable potencialmente. Esta vulnerabilidad afecta a Thunderbird versiones anteriores a la versión 68.3, Firefox ESR versiones anteriores a la versión 68.3 y Firefox versiones anteriores a la versión 71. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00001.html https://access.redhat.com/errata/RHSA-2020:0292 https://access.redhat.com/errata/RHSA-2020:0295 https://bugzilla.mozilla.org/show_bug.cgi?id=1584170 https://security.gentoo.org/glsa/202003-02 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4241-1 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/secur • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
