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-2023-4573, CVE-2023-4574,
CVE-2023-4575, CVE-2023-4581, CVE-2023-4584)

It was discovered that Thunderbird did not properly manage memory when
handling WebP images. If a user were tricked into opening a malicious WebP
image file, an attacker could potentially exploit these to cause a denial
of service or execute arbitrary code. (CVE-2023-4863)
