| CVE-2017-3735 | 3 Debian, Openssl, Redhat | 3 Debian Linux, Openssl, Enterprise Linux | 2025-04-20 | N/A |
| While parsing an IPAddressFamily extension in an X.509 certificate, it is possible to do a one-byte overread. This would result in an incorrect text display of the certificate. This bug has been present since 2006 and is present in all versions of OpenSSL before 1.0.2m and 1.1.0g. | ||||
| CVE-2017-3732 | 3 Nodejs, Openssl, Redhat | 5 Node.js, Openssl, Jboss Core Services and 2 more | 2025-04-20 | 5.9 Medium |
| There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL 1.0.2 before 1.0.2k and 1.1.0 before 1.1.0d. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. For example this can occur by default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very similar to CVE-2015-3193 but must be treated as a separate problem. | ||||
| CVE-2017-3733 | 2 Hp, Openssl | 2 Operations Agent, Openssl | 2025-04-20 | N/A |
| During a renegotiation handshake if the Encrypt-Then-Mac extension is negotiated where it was not in the original handshake (or vice-versa) then this can cause OpenSSL 1.1.0 before 1.1.0e to crash (dependent on ciphersuite). Both clients and servers are affected. | ||||
| CVE-2016-7053 | 1 Openssl | 1 Openssl | 2025-04-20 | N/A |
| In OpenSSL 1.1.0 before 1.1.0c, applications parsing invalid CMS structures can crash with a NULL pointer dereference. This is caused by a bug in the handling of the ASN.1 CHOICE type in OpenSSL 1.1.0 which can result in a NULL value being passed to the structure callback if an attempt is made to free certain invalid encodings. Only CHOICE structures using a callback which do not handle NULL value are affected. | ||||
| CVE-2017-3730 | 2 Openssl, Oracle | 7 Openssl, Agile Engineering Data Management, Communications Application Session Controller and 4 more | 2025-04-20 | N/A |
| In OpenSSL 1.1.0 before 1.1.0d, if a malicious server supplies bad parameters for a DHE or ECDHE key exchange then this can result in the client attempting to dereference a NULL pointer leading to a client crash. This could be exploited in a Denial of Service attack. | ||||
| CVE-2017-3736 | 2 Openssl, Redhat | 5 Openssl, Enterprise Linux, Jboss Core Services and 2 more | 2025-04-20 | N/A |
| There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL before 1.0.2m and 1.1.0 before 1.1.0g. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. This only affects processors that support the BMI1, BMI2 and ADX extensions like Intel Broadwell (5th generation) and later or AMD Ryzen. | ||||
| CVE-2016-7054 | 1 Openssl | 1 Openssl | 2025-04-20 | N/A |
| In OpenSSL 1.1.0 before 1.1.0c, TLS connections using *-CHACHA20-POLY1305 ciphersuites are susceptible to a DoS attack by corrupting larger payloads. This can result in an OpenSSL crash. This issue is not considered to be exploitable beyond a DoS. | ||||
| CVE-2016-0705 | 6 Canonical, Debian, Google and 3 more | 9 Ubuntu Linux, Debian Linux, Android and 6 more | 2025-04-12 | N/A |
| Double free vulnerability in the dsa_priv_decode function in crypto/dsa/dsa_ameth.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a malformed DSA private key. | ||||
| 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-2015-0287 | 2 Openssl, Redhat | 3 Openssl, Enterprise Linux, Storage | 2025-04-12 | N/A |
| The ASN1_item_ex_d2i function in crypto/asn1/tasn_dec.c 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 does not reinitialize CHOICE and ADB data structures, which might allow attackers to cause a denial of service (invalid write operation and memory corruption) by leveraging an application that relies on ASN.1 structure reuse. | ||||
| 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-2015-0286 | 2 Openssl, Redhat | 4 Openssl, Enterprise Linux, Jboss Core Services and 1 more | 2025-04-12 | N/A |
| The ASN1_TYPE_cmp function in crypto/asn1/a_type.c 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 does not properly perform boolean-type comparisons, which allows remote attackers to cause a denial of service (invalid read operation and application crash) via a crafted X.509 certificate to an endpoint that uses the certificate-verification feature. | ||||
| CVE-2015-0288 | 2 Openssl, Redhat | 4 Openssl, Enterprise Linux, Jboss Enterprise Web Server and 1 more | 2025-04-12 | N/A |
| The X509_to_X509_REQ function in crypto/x509/x509_req.c 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 might allow attackers to cause a denial of service (NULL pointer dereference and application crash) via an invalid certificate key. | ||||
| CVE-2015-0205 | 2 Openssl, Redhat | 2 Openssl, Enterprise Linux | 2025-04-12 | N/A |
| The ssl3_get_cert_verify function in s3_srvr.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k accepts client authentication with a Diffie-Hellman (DH) certificate without requiring a CertificateVerify message, which allows remote attackers to obtain access without knowledge of a private key via crafted TLS Handshake Protocol traffic to a server that recognizes a Certification Authority with DH support. | ||||
| CVE-2014-3506 | 2 Openssl, Redhat | 5 Openssl, Enterprise Linux, Jboss Enterprise Application Platform and 2 more | 2025-04-12 | N/A |
| d1_both.c in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i allows remote attackers to cause a denial of service (memory consumption) via crafted DTLS handshake messages that trigger memory allocations corresponding to large length values. | ||||
| CVE-2016-2842 | 2 Openssl, Redhat | 4 Openssl, Enterprise Linux, Jboss Core Services and 1 more | 2025-04-12 | N/A |
| The doapr_outch function in crypto/bio/b_print.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g does not verify that a certain memory allocation succeeds, which allows remote attackers to cause a denial of service (out-of-bounds write or memory consumption) 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-2016-0799. | ||||
| CVE-2015-0206 | 2 Openssl, Redhat | 2 Openssl, Enterprise Linux | 2025-04-12 | N/A |
| Memory leak in the dtls1_buffer_record function in d1_pkt.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k allows remote attackers to cause a denial of service (memory consumption) by sending many duplicate records for the next epoch, leading to failure of replay detection. | ||||
| CVE-2015-3194 | 5 Canonical, Debian, Nodejs and 2 more | 6 Ubuntu Linux, Debian Linux, Node.js and 3 more | 2025-04-12 | 7.5 High |
| crypto/rsa/rsa_ameth.c in OpenSSL 1.0.1 before 1.0.1q and 1.0.2 before 1.0.2e allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an RSA PSS ASN.1 signature that lacks a mask generation function parameter. | ||||
| 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-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. | ||||
