CVE-2023-29483
First published: Thu Apr 11 2024(Updated: )
Dnspython is vulnerable to a denial of service, caused by a flaw in stub resolver when a bad-in-some-way response arrives before a legitimate one on the UDP port dnspython is using for that query. By sending a specially crafted query, a remote attacker could exploit this vulnerability to cause a denial of service condition.
