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-2020-6799
Command line arguments could have been injected during Firefox invocation as a shell handler for certain unsupported file types. This required Firefox to be configured as the default handler for a given file type and for a file downloaded to be opened in a third party application that insufficiently sanitized URL data. In that situation, clicking a link in the third party application could have been used to retrieve and execute files whose location was supplied through command line arguments. Note: This issue only affects Windows operating systems and when Firefox is configured as the default handler for non-default filetypes. Other operating systems are unaffected. • https://bugzilla.mozilla.org/show_bug.cgi?id=1606596 https://security.gentoo.org/glsa/202003-02 https://www.mozilla.org/security/advisories/mfsa2020-05 https://www.mozilla.org/security/advisories/mfsa2020-06 • CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •

https://notcve.org/view.php?id=CVE-2020-6797
By downloading a file with the .fileloc extension, a semi-privileged extension could launch an arbitrary application on the user's computer. The attacker is restricted as they are unable to download non-quarantined files or supply command line arguments to the application, limiting the impact. Note: this issue only occurs on Mac OSX. Other operating systems are unaffected. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5. • https://bugzilla.mozilla.org/show_bug.cgi?id=1596668 https://security.gentoo.org/glsa/202003-02 https://www.mozilla.org/security/advisories/mfsa2020-05 https://www.mozilla.org/security/advisories/mfsa2020-06 https://www.mozilla.org/security/advisories/mfsa2020-07 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2020-6796
A content process could have modified shared memory relating to crash reporting information, crash itself, and cause an out-of-bound write. This could have caused memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 73 and Firefox < ESR68.5. Un procesamiento de contenido podría haber modificado una memoria compartida relacionada con la información de los reportes de bloqueos de aplicación, el bloqueo en sí mismo, y causar una escritura fuera de límites. Esto podría haber causado una corrupción de memoria y un bloqueo potencialmente explotable. • https://bugzilla.mozilla.org/show_bug.cgi?id=1610426 https://security.gentoo.org/glsa/202003-02 https://usn.ubuntu.com/4278-2 https://www.mozilla.org/security/advisories/mfsa2020-05 https://www.mozilla.org/security/advisories/mfsa2020-06 https://access.redhat.com/security/cve/CVE-2020-6796 https://bugzilla.redhat.com/show_bug.cgi?id=1801916 • CWE-787: Out-of-bounds Write •
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.
