- 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, 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)
