| An issue was discovered in openfortivpn 1.11.0 when used with OpenSSL before 1.0.2. tunnel.c mishandles certificate validation because hostname comparisons do not consider '\0' characters, as demonstrated by a good.example.com\x00evil.example.com attack. | |||||
| CVE-2020-7041 | 4 Fedoraproject, Openfortivpn Project, Openssl and 1 more | 5 Fedora, Openfortivpn, Openssl and 2 more | 2023-11-07 | 5.0 MEDIUM | 5.3 MEDIUM |
| An issue was discovered in openfortivpn 1.11.0 when used with OpenSSL 1.0.2 or later. tunnel.c mishandles certificate validation because an X509_check_host negative error code is interpreted as a successful return value. | |||||
| CVE-2020-7042 | 4 Fedoraproject, Openfortivpn Project, Openssl and 1 more | 5 Fedora, Openfortivpn, Openssl and 2 more | 2023-11-07 | 5.0 MEDIUM | 5.3 MEDIUM |
| An issue was discovered in openfortivpn 1.11.0 when used with OpenSSL 1.0.2 or later. tunnel.c mishandles certificate validation because the hostname check operates on uninitialized memory. The outcome is that a valid certificate is never accepted (only a malformed certificate may be accepted). | |||||
| CVE-2020-6529 | 4 Debian, Fedoraproject, Google and 1 more | 5 Debian Linux, Fedora, Chrome and 2 more | 2023-11-07 | 4.3 MEDIUM | 4.3 MEDIUM |
| Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a privileged network position to leak cross-origin data via a crafted HTML page. | |||||
| CVE-2020-35733 | 2 Erlang, Fedoraproject | 2 Erlang\/otp, Fedora | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Erlang/OTP before 23.2.2. The ssl application 10.2 accepts and trusts an invalid X.509 certificate chain to a trusted root Certification Authority. | |||||
| CVE-2020-28362 | 3 Fedoraproject, Golang, Netapp | 4 Fedora, Go, Cloud Insights Telegraf Agent and 1 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |

| CVE-2020-24661 | 2 Fedoraproject, Gnome | 2 Fedora, Geary | 2023-11-07 | 2.6 LOW | 5.9 MEDIUM |
| GNOME Geary before 3.36.3 mishandles pinned TLS certificate verification for IMAP and SMTP services using invalid TLS certificates (e.g., self-signed certificates) when the client system is not configured to use a system-provided PKCS#11 store. This allows a meddler in the middle to present a different invalid certificate to intercept incoming and outgoing mail. | |||||
| CVE-2020-1758 | 1 Redhat | 2 Keycloak, Openstack | 2023-11-07 | 4.3 MEDIUM | 5.9 MEDIUM |
| A flaw was found in Keycloak in versions before 10.0.0, where it does not perform the TLS hostname verification while sending emails using the SMTP server. This flaw allows an attacker to perform a man-in-the-middle (MITM) attack. | |||||
| CVE-2020-14039 | 2 Golang, Opensuse | 2 Go, Leap | 2023-11-07 | 5.0 MEDIUM | 5.3 MEDIUM |
| In Go before 1.13.13 and 1.14.x before 1.14.5, Certificate.Verify may lack a check on the VerifyOptions.KeyUsages EKU requirements (if VerifyOptions.Roots equals nil and the installation is on Windows). Thus, X.509 certificate verification is incomplete. | |||||
| CVE-2020-13482 | 2 Em-http-request Project, Fedoraproject | 2 Em-http-request, Fedora | 2023-11-07 | 5.8 MEDIUM | 7.4 HIGH |
| EM-HTTP-Request 1.1.5 uses the library eventmachine in an insecure way that allows an attacker to perform a man-in-the-middle attack against users of the library. The hostname in a TLS server certificate is not verified. | |||||
| CVE-2020-13614 | 3 Axel Project, Fedoraproject, Opensuse | 4 Axel, Fedora, Backports Sle and 1 more | 2023-11-07 | 4.3 MEDIUM | 5.9 MEDIUM |
| An issue was discovered in ssl.c in Axel before 2.17.8. The TLS implementation lacks hostname verification. | |||||
| CVE-2020-13645 | 5 Broadcom, Canonical, Fedoraproject and 2 more | 6 Fabric Operating System, Ubuntu Linux, Fedora and 3 more | 2023-11-07 | 6.4 MEDIUM | 6.5 MEDIUM |
| In GNOME glib-networking through 2.64.2, the implementation of GTlsClientConnection skips hostname verification of the server's TLS certificate if the application fails to specify the expected server identity. This is in contrast to its intended documented behavior, to fail the certificate verification. Applications that fail to provide the server identity, including Balsa before 2.5.11 and 2.6.x before 2.6.1, accept a TLS certificate if the certificate is valid for any host. | |||||
| CVE-2020-13254 | 6 Canonical, Debian, Djangoproject and 3 more | 7 Ubuntu Linux, Debian Linux, Django and 4 more | 2023-11-07 | 4.3 MEDIUM | 5.9 MEDIUM |
| An issue was discovered in Django 2.2 before 2.2.13 and 3.0 before 3.0.7. In cases where a memcached backend does not perform key validation, passing malformed cache keys could result in a key collision, and potential data leakage. | |||||
| CVE-2019-3814 | 3 Canonical, Dovecot, Opensuse | 3 Ubuntu Linux, Dovecot, Leap | 2023-11-07 | 4.9 MEDIUM | 6.8 MEDIUM |
| It was discovered that Dovecot before versions 2.2.36.1 and 2.3.4.1 incorrectly handled client certificates. A remote attacker in possession of a valid certificate with an empty username field could possibly use this issue to impersonate other users. | |||||
| CVE-2019-1552 | 1 Openssl | 1 Openssl | 2023-11-07 | 1.9 LOW | 3.3 LOW |
| OpenSSL has internal defaults for a directory tree where it can find a configuration file as well as certificates used for verification in TLS. This directory is most commonly referred to as OPENSSLDIR, and is configurable with the --prefix / --openssldir configuration options. For OpenSSL versions 1.1.0 and 1.1.1, the mingw configuration targets assume that resulting programs and libraries are installed in a Unix-like environment and the default prefix for program installation as well as for OPENSSLDIR should be '/usr/local'. However, mingw programs are Windows programs, and as such, find themselves looking at sub-directories of 'C:/usr/local', which may be world writable, which enables untrusted users to modify OpenSSL's default configuration, insert CA certificates, modify (or even replace) existing engine modules, etc. For OpenSSL 1.0.2, '/usr/local/ssl' is used as default for OPENSSLDIR on all Unix and Windows targets, including Visual C builds. However, some build instructions for the diverse Windows targets on 1.0.2 encourage you to specify your own --prefix. OpenSSL versions 1.1.1, 1.1.0 and 1.0.2 are affected by this issue. Due to the limited scope of affected deployments this has been assessed as low severity and therefore we are not creating new releases at this time. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL 1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s). | |||||
| CVE-2019-19270 | 2 Fedoraproject, Proftpd | 2 Fedora, Proftpd | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in tls_verify_crl in ProFTPD through 1.3.6b. Failure to check for the appropriate field of a CRL entry (checking twice for subject, rather than once for subject and once for issuer) prevents some valid CRLs from being taken into account, and can allow clients whose certificates have been revoked to proceed with a connection to the server. | |||||
| CVE-2019-11674 | 1 Microfocus | 1 Netiq Self Service Password Reset | 2023-11-07 | 4.3 MEDIUM | 5.9 MEDIUM |
| Man-in-the-middle vulnerability in Micro Focus Self Service Password Reset, affecting all versions prior to 4.4.0.4. The vulnerability could exploit invalid certificate validation and may result in a man-in-the-middle attack. | |||||
| CVE-2019-13050 | 5 F5, Fedoraproject, Gnupg and 2 more | 5 Traffix Signaling Delivery Controller, Fedora, Gnupg and 2 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| Interaction between the sks-keyserver code through 1.2.0 of the SKS keyserver network, and GnuPG through 2.2.16, makes it risky to have a GnuPG keyserver configuration line referring to a host on the SKS keyserver network. Retrieving data from this network may cause a persistent denial of service, because of a Certificate Spamming Attack. | |||||
| CVE-2019-11324 | 2 Canonical, Python | 2 Ubuntu Linux, Urllib3 | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| The urllib3 library before 1.24.2 for Python mishandles certain cases where the desired set of CA certificates is different from the OS store of CA certificates, which results in SSL connections succeeding in situations where a verification failure is the correct outcome. This is related to use of the ssl_context, ca_certs, or ca_certs_dir argument. | |||||
| CVE-2018-8019 | 2 Apache, Debian | 2 Tomcat Native, Debian Linux | 2023-11-07 | 4.3 MEDIUM | 7.4 HIGH |
| When using an OCSP responder Apache Tomcat Native 1.2.0 to 1.2.16 and 1.1.23 to 1.1.34 did not correctly handle invalid responses. This allowed for revoked client certificates to be incorrectly identified. It was therefore possible for users to authenticate with revoked certificates when using mutual TLS. Users not using OCSP checks are not affected by this vulnerability. | |||||
