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, or execute arbitrary code. (CVE-2021-23968,
CVE-2021-23969, CVE-2021-23973, CVE-2021-23978)
It was discovered that Thunderbird may keep key material in memory in some
circumstances. A local attacker could potentially exploit this to obtain
private keys. (CVE-2021-29950)
