CVE-2020-35679 2 Fedoraproject, Opensmtpd 2 Fedora, Opensmtpd 2022-04-26 5.0 MEDIUM 7.5 HIGH

CVE-2020-35680 2 Fedoraproject, Opensmtpd 2 Fedora, Opensmtpd 2021-05-26 5.0 MEDIUM 7.5 HIGH
smtpd/lka_filter.c in OpenSMTPD before 6.8.0p1, in certain configurations, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted pattern of client activity, because the filter state machine does not properly maintain the I/O channel between the SMTP engine and the filters layer.
