certain tarfile headers. A remote attacker could possibly use this issue to
cause Python to consume resources, leading to a denial of service.
(CVE-2024-6232)
It was discovered that the Python email module incorrectly quoted newlines
for email headers. A remote attacker could possibly use this issue to
perform header injection. (CVE-2024-6923)

parsing cookies that contained backslashes for quoted characters. A remote
attacker could possibly use this issue to cause Python to consume
resources, leading to a denial of service. (CVE-2024-7592)
It was discovered that the Python zipfile module incorrectly handled
certain malformed zip files. A remote attacker could possibly use this
issue to cause Python to stop responding, resulting in a denial of service.
