CVSS: 8.8EPSS: 0%CPEs: 6EXPL: 0CVE-2020-6800 – Mozilla: Memory safety bugs fixed in Firefox 73 and Firefox ESR 68.5
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. Los desarrolladores de Mozilla y los miembros de comunidad han reportado bugs de seguridad de la memoria presentes en Firefox versión 72 y Firefox ESR versión 68.4. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1595786%2C1596706%2C1598543%2C1604851%2C1608580%2C1608785%2C1605777 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&# • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2019-17023
After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3, resulting in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming Application Data records will be ignored. This vulnerability affects Firefox < 72. Después de que HelloRetryRequest haya sido enviado, el cliente puede negociar un protocolo inferior que TLS versión 1.3, resultando en una transición de estado no válida en TLS State Machine. Si el cliente entra en este estado, los registros de Datos de Aplicación entrantes serian ignorados. • https://bugzilla.mozilla.org/show_bug.cgi?id=1590001 https://usn.ubuntu.com/4234-1 https://usn.ubuntu.com/4397-1 https://www.debian.org/security/2020/dsa-4726 https://www.mozilla.org/security/advisories/mfsa2020-01 https://access.redhat.com/security/cve/CVE-2019-17023 https://bugzilla.redhat.com/show_bug.cgi?id=1791225 • CWE-287: Improper Authentication •
