CVSS: 6.5EPSS: 0%CPEs: 4EXPL: 1CVE-2020-6794 – Mozilla: Setting a master password post-Thunderbird 52 does not delete unencrypted previously stored passwords
https://notcve.org/view.php?id=CVE-2020-6794
If a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Thunderbird 60. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Thunderbird < 68.5. • https://bugzilla.mozilla.org/show_bug.cgi?id=1606619 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4328-1 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2020-07 https://access.redhat.com/security/cve/CVE-2020-6794 https://bugzilla.redhat.com/show_bug.cgi?id=1801956 • CWE-312: Cleartext Storage of Sensitive Information CWE-459: Incomplete Cleanup CWE-522: Insufficiently Protected Credentials •

CVSS: 4.3EPSS: 0%CPEs: 4EXPL: 0CVE-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 •
