Summary
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-2024-4767, CVE-2024-4768,
CVE-2024-4769, CVE-2024-4777)
Thomas Rinsma discovered that Thunderbird did not properly handle type check
when handling fonts in PDF.js. An attacker could potentially exploit this
issue to execute arbitrary javascript code in PDF.js. (CVE-2024-4367)
Irvan Kurniawan discovered that Thunderbird did not properly handle certain
font styles when saving a page to PDF. An attacker could potentially
