If a MIME email combines OpenPGP and OpenPGP MIME data in a certain way Thunderbird repeatedly attempts to process and display the message, which could cause Thunderbird's user interface to lock up and no longer respond to the user's actions. An attacker could send a crafted message with this structure to attempt a DoS attack. This vulnerability affects Thunderbird < 102.8.

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. An attacker could possibly use this issue to spoof the user and obtain 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 PKCS 12 certificate. (CVE-2023-0767)

Ronald Crane discovered that Thunderbird did not properly check the size of the input being encoded in xpcom. An attacker could possibly use this issue to perform out of bound memory write operations. (CVE-2023-25732)
