CVE-2016-7444 2 Gnu, Redhat 2 Gnutls, Enterprise Linux 2025-04-12 N/A
The gnutls_ocsp_resp_check_crt function in lib/x509/ocsp.c in GnuTLS before 3.4.15 and 3.5.x before 3.5.4 does not verify the serial length of an OCSP response, which might allow remote attackers to bypass an intended certificate validation mechanism via vectors involving trailing bytes left by gnutls_malloc.
CVE-2014-3691 2 Redhat, Theforeman 5 Openstack, Openstack-installer, Satellite and 2 more 2025-04-12 N/A
Smart Proxy (aka Smart-Proxy and foreman-proxy) in Foreman before 1.5.4 and 1.6.x before 1.6.2 does not validate SSL certificates, which allows remote attackers to bypass intended authentication and execute arbitrary API requests via a request without a certificate.
CVE-2015-0282 2 Gnu, Redhat 2 Gnutls, Enterprise Linux 2025-04-12 N/A
GnuTLS before 3.1.0 does not verify that the RSA PKCS #1 signature algorithm matches the signature algorithm in the certificate, which allows remote attackers to conduct downgrade attacks via unspecified vectors.
CVE-2016-5419 4 Debian, Haxx, Opensuse and 1 more 6 Debian Linux, Libcurl, Leap and 3 more 2025-04-12 N/A
curl and libcurl before 7.50.1 do not prevent TLS session resumption when the client certificate has changed, which allows remote attackers to bypass intended restrictions by resuming a session.
CVE-2014-3522 4 Apache, Apple, Canonical and 1 more 4 Subversion, Xcode, Ubuntu Linux and 1 more 2025-04-12 N/A
The Serf RA layer in Apache Subversion 1.4.0 through 1.7.x before 1.7.18 and 1.8.x before 1.8.10 does not properly handle wildcards in the Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.
CVE-2014-7144 2 Openstack, Redhat 3 Keystonemiddleware, Python-keystoneclient, Openstack 2025-04-12 N/A
OpenStack keystonemiddleware (formerly python-keystoneclient) 0.x before 0.11.0 and 1.x before 1.2.0 disables certification verification when the "insecure" option is set in a paste configuration (paste.ini) file regardless of the value, which allows remote attackers to conduct man-in-the-middle attacks via a crafted certificate.
CVE-2014-8151 2 Apple, Haxx 2 Mac Os X, Libcurl 2025-04-12 N/A
The darwinssl_connect_step1 function in lib/vtls/curl_darwinssl.c in libcurl 7.31.0 through 7.39.0, when using the DarwinSSL (aka SecureTransport) back-end for TLS, does not check if a cached TLS session validated the certificate when reusing the session, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.
CVE-2016-5420 4 Debian, Haxx, Opensuse and 1 more 6 Debian Linux, Libcurl, Leap and 3 more 2025-04-12 N/A
curl and libcurl before 7.50.1 do not check the client certificate when choosing the TLS connection to reuse, which might allow remote attackers to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate.
CVE-2024-39312 2 Botan Project, Randombit 2 Botan, Botan 2025-04-11 5.3 Medium
Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an object identifier or using explicit encoding of the parameters. A bug in the parsing of name constraint extensions in X.509 certificates meant that if the extension included both permitted subtrees and excluded subtrees, only the permitted subtree would be checked. If a certificate included a name which was permitted by the permitted subtree but also excluded by excluded subtree, it would be accepted. Fixed in versions 3.5.0 and 2.19.5.
CVE-2012-5821 2 Canonical, Lynx 2 Ubuntu Linux, Lynx 2025-04-11 5.9 Medium
Lynx does not verify that the server's certificate is signed by a trusted certification authority, which allows man-in-the-middle attackers to spoof SSL servers via a crafted certificate, related to improper use of a certain GnuTLS function.
CVE-2012-4948 1 Fortinet 29 Fortigate-1000c, Fortigate-100d, Fortigate-110c and 26 more 2025-04-11 N/A
The default configuration of Fortinet Fortigate UTM appliances uses the same Certification Authority certificate and same private key across different customers' installations, which makes it easier for man-in-the-middle attackers to spoof SSL servers by leveraging the presence of the Fortinet_CA_SSLProxy certificate in a list of trusted root certification authorities.
CVE-2011-3024 1 Google 1 Chrome 2025-04-11 N/A
Google Chrome before 17.0.963.56 allows remote attackers to cause a denial of service (application crash) via an empty X.509 certificate.
CVE-2012-0861 1 Redhat 3 Enterprise Linux, Enterprise Virtualization Manager, Rhev Manager 2025-04-11 N/A
The vds_installer in Red Hat Enterprise Virtualization Manager (RHEV-M) before 3.1, when adding a host, uses the -k curl parameter when downloading deployUtil.py and vds_bootstrap.py, which prevents SSL certificates from being validated and allows remote attackers to execute arbitrary Python code via a man-in-the-middle attack.
CVE-2010-1378 1 Apple 2 Mac Os X, Mac Os X Server 2025-04-11 9.8 Critical
OpenSSL in Apple Mac OS X 10.6.x before 10.6.5 does not properly perform arithmetic, which allows remote attackers to bypass X.509 certificate authentication via an arbitrary certificate issued by a legitimate Certification Authority.
CVE-2011-3061 1 Google 1 Chrome 2025-04-11 N/A
Google Chrome before 18.0.1025.142 does not properly check X.509 certificates before use of a SPDY proxy, which might allow man-in-the-middle attackers to spoof servers or obtain sensitive information via a crafted certificate.
CVE-2012-3446 1 Apache 1 Libcloud 2025-04-11 5.9 Medium
Apache Libcloud before 0.11.1 uses an incorrect regular expression during verification of whether the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a crafted certificate.
CVE-2014-1266 1 Apple 3 Iphone Os, Mac Os X, Tvos 2025-04-11 7.4 High
The SSLVerifySignedServerKeyExchange function in libsecurity_ssl/lib/sslKeyExchange.c in the Secure Transport feature in the Data Security component in Apple iOS 6.x before 6.1.6 and 7.x before 7.0.6, Apple TV 6.x before 6.0.2, and Apple OS X 10.9.x before 10.9.2 does not check the signature in a TLS Server Key Exchange message, which allows man-in-the-middle attackers to spoof SSL servers by (1) using an arbitrary private key for the signing step or (2) omitting the signing step.
CVE-2012-5824 1 Cerulean Studios 1 Trillian 2025-04-11 N/A
Trillian 5.1.0.19 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate, a different vulnerability than CVE-2009-4831.
CVE-2011-0199 1 Apple 2 Mac Os X, Mac Os X Server 2025-04-11 5.9 Medium
The Certificate Trust Policy component in Apple Mac OS X before 10.6.8 does not perform CRL checking for Extended Validation (EV) certificates that lack OCSP URLs, which might allow man-in-the-middle attackers to spoof an SSL server via a revoked certificate.
CVE-2011-2874 1 Google 1 Chrome 2025-04-11 N/A
Google Chrome before 14.0.835.163 does not perform an expected pin operation for a self-signed certificate during a session, which has unspecified impact and remote attack vectors.
