Details

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-2023-4057, CVE-2023-4577,
CVE-2023-4578, CVE-2023-4583, CVE-2023-4585, CVE-2023-5169, CVE-2023-5171,
CVE-2023-5176)

Andrew McCreight discovered that Thunderbird did not properly manage during
the worker lifecycle. An attacker could potentially exploit this issue to
cause a denial of service. (CVE-2023-3600)

Harveer Singh discovered that Thunderbird did not store push notifications
in private browsing mode in encrypted form. An attacker could potentially
exploit this issue to obtain sensitive information. (CVE-2023-4580)

Clément Lecigne discovered that Thunderbird did not properly manage memory
when handling VP8 media stream. An attacker-controlled VP8 media stream
could lead to a heap buffer overflow in the content process, resulting in a
denial of service, or possibly execute arbitrary code. (CVE-2023-5217)
