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-2024-5688, CVE-2024-5690,
CVE-2024-5696, CVE-2024-5700, CVE-2024-5702)

Luan Herrera discovered that Thunderbird did not properly validate the
X-Frame-Options header inside sandboxed iframe. An attacker could
potentially exploit this issue to bypass sandbox restrictions to open a new
window. (CVE-2024-5691)

Kirtikumar Anandrao Ramchandani discovered that Thunderbird did not properly
track cross-origin tainting in Offscreen Canvas. An attacker could
potentially exploit this issue to access image data from another site in
violation of same-origin policy. (CVE-2024-5693)
