Vulnerability Insight:

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, conduct spoofing attacks, bypass security
restrictions, or execute arbitrary code. (CVE-2021-4129, CVE-2021-4140,

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)
