| CVE-2020-8794 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2022-10-07 | 10.0 HIGH | 9.8 CRITICAL |
| OpenSMTPD before 6.6.4 allows remote code execution because of an out-of-bounds read in mta_io in mta_session.c for multi-line replies. Although this vulnerability affects the client side of OpenSMTPD, it is possible to attack a server because the server code launches the client code during bounce handling. | |||||
| CVE-2020-35680 | 2 Fedoraproject, Opensmtpd | 2 Fedora, Opensmtpd | 2022-09-01 | 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. | |||||
| CVE-2020-35679 | 2 Fedoraproject, Opensmtpd | 2 Fedora, Opensmtpd | 2022-04-26 | 5.0 MEDIUM | 7.5 HIGH |
| smtpd/table.c in OpenSMTPD before 6.8.0p1 lacks a certain regfree, which might allow attackers to trigger a "very significant" memory leak via messages to an instance that performs many regex lookups. | |||||
| CVE-2020-8793 | 3 Canonical, Fedoraproject, Opensmtpd | 3 Ubuntu Linux, Fedora, Opensmtpd | 2022-01-01 | 4.7 MEDIUM | 4.7 MEDIUM |
| OpenSMTPD before 6.6.4 allows local users to read arbitrary files (e.g., on some Linux distributions) because of a combination of an untrusted search path in makemap.c and race conditions in the offline functionality in smtpd.c. | |||||
