CVE-2016-0701 1 Openssl 1 Openssl 2025-04-12 N/A
The DH_check_pub_key function in crypto/dh/dh_check.c in OpenSSL 1.0.2 before 1.0.2f does not ensure that prime numbers are appropriate for Diffie-Hellman (DH) key exchange, which makes it easier for remote attackers to discover a private DH exponent by making multiple handshakes with a peer that chose an inappropriate number, as demonstrated by a number in an X9.42 file.
CVE-2016-0704 2 Openssl, Redhat 6 Openssl, Enterprise Linux, Rhel Aus and 3 more 2025-04-12 N/A
An oracle protection mechanism in the get_client_master_key function in s2_srvr.c in the SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a overwrites incorrect MASTER-KEY bytes during use of export cipher suites, which makes it easier for remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, a related issue to CVE-2016-0800.
CVE-2016-0799 3 Openssl, Pulsesecure, Redhat 6 Openssl, Client, Steel Belted Radius and 3 more 2025-04-12 N/A
The fmtstr function in crypto/bio/b_print.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g improperly calculates string lengths, which allows remote attackers to cause a denial of service (overflow and out-of-bounds read) or possibly have unspecified other impact via a long string, as demonstrated by a large amount of ASN.1 data, a different vulnerability than CVE-2016-2842.
CVE-2014-0076 1 Openssl 1 Openssl 2025-04-12 N/A
The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack.
CVE-2016-6309 1 Openssl 1 Openssl 2025-04-12 N/A
statem/statem.c in OpenSSL 1.1.0a does not consider memory-block movement after a realloc call, which allows remote attackers to cause a denial of service (use-after-free) or possibly execute arbitrary code via a crafted TLS session.
CVE-2016-2176 1 Openssl 1 Openssl 2025-04-12 N/A
The X509_NAME_oneline function in crypto/x509/x509_obj.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to obtain sensitive information from process stack memory or cause a denial of service (buffer over-read) via crafted EBCDIC ASN.1 data.
CVE-2015-0207 1 Openssl 1 Openssl 2025-04-12 N/A
The dtls1_listen function in d1_lib.c in OpenSSL 1.0.2 before 1.0.2a does not properly isolate the state information of independent data streams, which allows remote attackers to cause a denial of service (application crash) via crafted DTLS traffic, as demonstrated by DTLS 1.0 traffic to a DTLS 1.2 server.
CVE-2015-1787 1 Openssl 1 Openssl 2025-04-12 N/A
The ssl3_get_client_key_exchange function in s3_srvr.c in OpenSSL 1.0.2 before 1.0.2a, when client authentication and an ephemeral Diffie-Hellman ciphersuite are enabled, allows remote attackers to cause a denial of service (daemon crash) via a ClientKeyExchange message with a length of zero.
CVE-2015-3216 2 Openssl, Redhat 3 Openssl, Enterprise Linux, Jboss Core Services 2025-04-12 N/A
Race condition in a certain Red Hat patch to the PRNG lock implementation in the ssleay_rand_bytes function in OpenSSL, as distributed in openssl-1.0.1e-25.el7 in Red Hat Enterprise Linux (RHEL) 7 and other products, allows remote attackers to cause a denial of service (application crash) by establishing many TLS sessions to a multithreaded server, leading to use of a negative value for a certain length field.
CVE-2016-6302 3 Openssl, Oracle, Redhat 5 Openssl, Linux, Solaris and 2 more 2025-04-12 N/A
The tls_decrypt_ticket function in ssl/t1_lib.c in OpenSSL before 1.1.0 does not consider the HMAC size during validation of the ticket length, which allows remote attackers to cause a denial of service via a ticket that is too short.
CVE-2014-0195 5 Fedoraproject, Mariadb, Openssl and 2 more 7 Fedora, Mariadb, Openssl and 4 more 2025-04-12 N/A
The dtls1_reassemble_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly validate fragment lengths in DTLS ClientHello messages, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via a long non-initial fragment.
CVE-2014-0224 9 Fedoraproject, Filezilla-project, Mariadb and 6 more 23 Fedora, Filezilla Server, Mariadb and 20 more 2025-04-12 7.4 High
OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the "CCS Injection" vulnerability.
CVE-2015-0204 2 Openssl, Redhat 4 Openssl, Enterprise Linux, Jboss Enterprise Application Platform and 1 more 2025-04-12 N/A
The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct RSA-to-EXPORT_RSA downgrade attacks and facilitate brute-force decryption by offering a weak ephemeral RSA key in a noncompliant role, related to the "FREAK" issue. NOTE: the scope of this CVE is only client code based on OpenSSL, not EXPORT_RSA issues associated with servers or other TLS implementations.
CVE-2015-3195 9 Apple, Canonical, Debian and 6 more 28 Mac Os X, Ubuntu Linux, Debian Linux and 25 more 2025-04-12 5.3 Medium
The ASN1_TFLG_COMBINE implementation in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zh, 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1q, and 1.0.2 before 1.0.2e mishandles errors caused by malformed X509_ATTRIBUTE data, which allows remote attackers to obtain sensitive information from process memory by triggering a decoding failure in a PKCS#7 or CMS application.
CVE-2015-4000 13 Apple, Canonical, Debian and 10 more 31 Iphone Os, Mac Os X, Safari and 28 more 2025-04-12 N/A
The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.
CVE-2016-2105 8 Apple, Canonical, Debian and 5 more 20 Mac Os X, Ubuntu Linux, Debian Linux and 17 more 2025-04-12 7.5 High
Integer overflow in the EVP_EncodeUpdate function in crypto/evp/encode.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (heap memory corruption) via a large amount of binary data.
CVE-2011-3207 2 Openssl, Redhat 2 Openssl, Enterprise Linux 2025-04-11 N/A
crypto/x509/x509_vfy.c in OpenSSL 1.0.x before 1.0.0e does not initialize certain structure members, which makes it easier for remote attackers to bypass CRL validation by using a nextUpdate value corresponding to a time in the past.
CVE-2011-4577 2 Openssl, Redhat 2 Openssl, Enterprise Linux 2025-04-11 N/A
OpenSSL before 0.9.8s and 1.x before 1.0.0f, when RFC 3779 support is enabled, allows remote attackers to cause a denial of service (assertion failure) via an X.509 certificate containing certificate-extension data associated with (1) IP address blocks or (2) Autonomous System (AS) identifiers.
CVE-2011-4619 2 Openssl, Redhat 4 Openssl, Enterprise Linux, Jboss Enterprise Application Platform and 1 more 2025-04-11 N/A
The Server Gated Cryptography (SGC) implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service (CPU consumption) via unspecified vectors.
CVE-2012-2333 2 Openssl, Redhat 5 Openssl, Enterprise Linux, Jboss Enterprise Application Platform and 2 more 2025-04-11 N/A
Integer underflow in OpenSSL before 0.9.8x, 1.0.0 before 1.0.0j, and 1.0.1 before 1.0.1c, when TLS 1.1, TLS 1.2, or DTLS is used with CBC encryption, allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via a crafted TLS packet that is not properly handled during a certain explicit IV calculation.
