CVE-2020-6797
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 •
CVE-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') •
