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, bypass security restrictions, cross-site
tracing, or execute arbitrary code. (CVE-2023-34414, CVE-2023-34416,
CVE-2023-37201, CVE-2023-37202, CVE-2023-37207, CVE-2023-37211)

P Umar Farooq discovered that Thunderbird did not properly provide warning
when opening Diagcab files. If a user were tricked into opening a
malicicous Diagcab file, an attacker could execute arbitrary code.
