Summary:

Several security issues were fixed in Thunderbird.

Software Description:
- thunderbird: Mozilla Open Source mail and newsgroup client

Details:

Multiple security issues were discovered in Thunderbird. If a user were

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)

image file, an attacker could potentially exploit these to cause a denial
of service or execute arbitrary code. (CVE-2023-4863)
