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-2023-1945, CVE-2023-29548, CVE-2023-29550)
Paul Menzel discovered that Thunderbird did not properly validate OCSP revocation status of recipient certificates when sending S/Mime encrypted email. An attacker could potentially exploits this issue to perform spoofing attack. (CVE-2023-0547)
Ribose RNP Team discovered that Thunderbird did not properly manage memory when parsing certain OpenPGP messages. An attacker could potentially exploits this issue to cause a denial of service. (CVE-2023-29479)
Irvan Kurniawan discovered that Thunderbird did not properly manage fullscreen notifications using a combination of window.open, fullscreen requests, window.name assignments, and setInterval calls. An attacker could potentially exploit this issue to perform spoofing attacks. (CVE-2023-29533)
Lukas Bernhard discovered that Thunderbird did not properly manage memory when doing Garbage Collector compaction. An attacker could potentially exploits this issue to cause a denial of service. (CVE-2023-29535)
Zx from qriousec discovered that Thunderbird did not properly validate the address to free a pointer provided to the memory manager. An attacker could potentially exploits this issue to cause a denial of service. (CVE-2023-29536)
