Details

Multiple security issues were discovered in Thunderbird. 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, trick a user into accepting unwanted
permissions, conduct header splitting attacks, conduct spoofing attacks,
bypass security restrictions, confuse the user, or execute arbitrary code.

It was discovered that Thunderbird ignored the configuration to require
STARTTLS for an SMTP connection. A person-in-the-middle could potentially
exploit this to perform a downgrade attack in order to intercept messages
or take control of a session. (CVE-2021-38502)

It was discovered that JavaScript was unexpectedly enabled in the
composition area. An attacker could potentially exploit this in
combination with another vulnerability, with unspecified impacts.
(CVE-2021-43528)

A buffer overflow was discovered in the Matrix chat library bundled with
Thunderbird. An attacker could potentially exploit this to cause a denial
of service, or execute arbitrary code. (CVE-2021-44538)

It was discovered that Thunderbird’s OpenPGP integration only considered
the inner signed message when checking signature validity in a message
that contains an additional outer MIME layer. An attacker could
potentially exploit this to trick the user into thinking that a message
has a valid signature. (CVE-2021-4126)
