Details

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,
obtain sensitive information, bypass security restrictions, bypass
same-origin restrictions, conduct cross-site scripting (XSS) attacks, or
execute arbitrary code. (CVE-2019-11757, CVE-2019-11758, CVE-2019-11759,
CVE-2019-11760, CVE-2019-11761, CVE-2019-11762, CVE-2019-11763,
CVE-2019-11764, CVE-2019-17005, CVE-2019-17008, CVE-2019-17010,
CVE-2019-17011, CVE-2019-17012, CVE-2019-17016, CVE-2019-17017,
CVE-2019-17022, CVE-2019-17024, CVE-2019-17026, 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 NSS incorrectly handled certain memory operations.
A remote attacker could potentially exploit this to cause a denial of
service, or execute arbitrary code. (CVE-2019-11745)

It was discovered that a specially crafted S/MIME message with an inner
encryption layer could be displayed as having a valid signature in some
circumstances, even if the signer had no access to the encrypted message.
An attacker could potentially exploit this to spoof the message author.
(CVE-2019-11755)

A heap overflow was discovered in the expat library in Thunderbird. If a
user were tricked in to opening a specially crafted message, an attacker
could potentially exploit this to cause a denial of service, or execute
arbitrary code. (CVE-2019-15903)

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 primary password, an unencrypted copy of these passwords
would still be accessible. A local user could exploit this to obtain
sensitive information. (CVE-2020-6794)

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)
