If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, spoof the UI, bypass security restrictions, or execute arbitrary code. ( CVE-2021-23961 , CVE-2021-23981 , CVE-2021-23982 , CVE-2021-23987 , CVE-2021-23994 , CVE-2021-23998 , CVE-2021-23999 , CVE-2021-29945 , CVE-2021-29946 , CVE-2021-29967 ) It was discovered that extensions could open popup windows with control of the window title in some circumstances. If a user were tricked into installing a specially crafted extension, an attacker could potentially exploit this to spoof a website and trick the user into providing credentials. ( CVE-2021-23984 ) Multiple security issues were discovered in Thunderbird's OpenPGP integration. If a user were tricked into importing a specially crafted key in some circumstances, an attacker could potentially exploit this to cause a denial of service (inability to send encrypted email) or confuse the user. ( CVE-2021-23991 , CVE-2021-23992 , CVE-2021-23993 ) A use-after-free was discovered when Responsive Design Mode was enabled.

( CVE-2021-23995 ) It was discovered that Thunderbird mishandled ftp URLs with encoded newline characters. If a user were tricked into clicking on a specially crafted link, an attacker could potentially exploit this to send arbitrary FTP commands.

A local attacker could potentially exploit this to replace the data with another signature file. ( CVE-2021-29948 ) It was discovered that Thunderbird might load an alternative OTR library. If a user were tricked into copying a specially crafted library to one of Thunderbird's search paths, an attacker could potentially exploit this to execute arbitrary code. ( CVE-2021-29949 ) It was discovered that secret keys imported into Thunderbird were stored unencrypted. A local attacker could potentially exploit this to obtain private keys. ( CVE-2021-29956 ) It was discovered that Thunderbird did not indicate when an inline signed or encrypted message contained additional unprotected parts.
