Summary
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,
or execute arbitrary code. (CVE-2020-6831, CVE-2020-12387, CVE-2020-12395)
It was discovered that the Devtools’ ‘Copy as cURL’ feature did not
properly escape the HTTP POST data of a request. 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 obtain sensitive information from local files.
(CVE-2020-12392)
It was discovered that Thunderbird did not correctly handle Unicode
whitespace characters within the From email header. An attacker could
potentially exploit this to spoof the sender email address that
Thunderbird displays. (CVE-2020-12397)
