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-2024-6600, CVE-2024-6601,
CVE-2024-6604)

Ronald Crane discovered that Thunderbird did not properly manage certain
memory operations in the NSS. An attacker could potentially exploit this
issue to cause a denial of service. (CVE-2024-6602)

Irvan Kurniawan discovered that Thunderbird did not properly manage memory
during thread creation. An attacker could potentially exploit this
issue to cause a denial of service, or execute arbitrary code.
