Details

Denis Andzakovic discovered that atftpd incorrectly handled certain malformed packets. A remote attacker could send a specially crafted packet to cause atftpd to crash, resulting in a denial of service. (CVE-2019-11365)

Denis Andzakovic discovered that atftpd did not properly lock the thread list mutex. An attacker could send a large number of tftpd packets simultaneously when running atftpd in daemon mode to cause atftpd to crash, resulting in a denial of service. (CVE-2019-11366)
