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-2023-0616, CVE-2023-25735,
CVE-2023-25737, CVE-2023-25739, CVE-2023-25729, CVE-2023-25742,
CVE-2023-25746)
Johan Carlsson discovered that Thunderbird did not properly implement CSP
policy on a header when using iframes. An attacker could potentially
exploits this to exfiltrate data. (CVE-2023-25728)
Irvan Kurniawan discovered that Thunderbird was not properly handling
background fullscreen scripts when the window goes into fullscreen mode.

sensitive information. (CVE-2023-25730)
Christian Holler discovered that Thunderbird did not properly check the
Safe Bag attributes in PKCS 12 certificate bundle. An attacker could
possibly use this issue to write to arbitrary memory by sending malicious
