    Summary: thunderbird vulnerabilities

    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)
