Summary
thunderbird vulnerabilities
Details

It was discovered that Message ID calculation was based on uninitialized data. An attacker could potentially exploit this to obtain sensitive information. (CVE-2020-6792)

Mutiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, or execute arbitrary code. (CVE-2020-6793, CVE-2020-6795, CVE-2020-6822)

It was discovered that if a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy of these passwords would still be accessible. A local user could exploit this to obtain sensitive information. (CVE-2020-6794)

Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, conduct cross-site scripting (XSS) attacks, obtain sensitive information, or execute arbitrary code. (CVE-2019-20503, CVE-2020-6798, CVE-2020-6800, CVE-2020-6805, CVE-2020-6806, CVE-2020-6807, CVE-2020-6812, CVE-2020-6814, CVE-2020-6819, CVE-2020-6820, CVE-2020-6821, CVE-2020-6825)

It was discovered that the Devtools’ ‘Copy as cURL’ feature did not fully escape website-controlled data. If a user were tricked in to using the ‘Copy as cURL’ feature to copy and paste a command with specially crafted data in to a terminal, an attacker could potentially exploit this to execute arbitrary commands via command injection. (CVE-2020-6811)

(CVE-2020-6793, CVE-2020-6795,\nCVE-2020-6822)\n\nIt was discovered that if a user saved passwords before Thunderbird 60\nand then later set a master password, an unencrypted copy of these\npasswords would still be accessible. A local user could exploit this to\nobtain sensitive information. (CVE-2020-6794)\n\nMultiple security issues were discovered in Thunderbird. If a user were\ntricked in to opening a specially crafted website in a browsing context,\nan attacker could potentially exploit these to cause a denial of service,\nconduct cross-site scripting (XSS) attacks, obtain sensitive information,\nor execute arbitrary code. (CVE-2019-20503, CVE-2020-6798, CVE-2020-6800,\nCVE-2020-6805, CVE-2020-6806, CVE-2020-6807, CVE-2020-6812, CVE-2020-6814,\nCVE-2020-6819, CVE-2020-6820, CVE-2020-6821, CVE-2020-6825)\n\nIt was discovered that the Devtools\u2019 \u2018Copy as cURL\u2019 feature did not\nfully escape website-controlled data. If a user were tricked in to using\nthe \u2018Copy as cURL\u2019 feature to copy and paste a command with specially\ncrafted data in to a terminal, an attacker could potentially exploit this\nto execute arbitrary commands via command injection.
