| CVE-2017-3737 | 3 Debian, Openssl, Redhat | 4 Debian Linux, Openssl, Enterprise Linux and 1 more | 2025-04-20 | N/A |
| OpenSSL 1.0.2 (starting from version 1.0.2b) introduced an "error state" mechanism. The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This works as designed for the explicit handshake functions (SSL_do_handshake(), SSL_accept() and SSL_connect()), however due to a bug it does not work correctly if SSL_read() or SSL_write() is called directly. In that scenario, if the handshake fails then a fatal error will be returned in the initial function call. If SSL_read()/SSL_write() is subsequently called by the application for the same SSL object then it will succeed and the data is passed without being decrypted/encrypted directly from the SSL/TLS record layer. In order to exploit this issue an application bug would have to be present that resulted in a call to SSL_read()/SSL_write() being issued after having already received a fatal error. OpenSSL version 1.0.2b-1.0.2m are affected. Fixed in OpenSSL 1.0.2n. OpenSSL 1.1.0 is not affected. | ||||

| 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. | ||||

| In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port. | ||||
| CVE-2016-7055 | 3 Nodejs, Openssl, Redhat | 3 Node.js, Openssl, Jboss Core Services | 2025-04-20 | 5.9 Medium |
| There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure in OpenSSL 1.0.2 and 1.1.0 before 1.1.0c that handles input lengths divisible by, but longer than 256 bits. Analysis suggests that attacks against RSA, DSA and DH private keys are impossible. This is because the subroutine in question is not used in operations with the private key itself and an input of the attacker's direct choice. Otherwise the bug can manifest itself as transient authentication and key negotiation failures or reproducible erroneous outcome of public-key operations with specially crafted input. Among EC algorithms only Brainpool P-512 curves are affected and one presumably can attack ECDH key negotiation. Impact was not analyzed in detail, because pre-requisites for attack are considered unlikely. Namely multiple clients have to choose the curve in question and the server has to share the private key among them, neither of which is default behaviour. Even then only clients that chose the curve will be affected. | ||||
| CVE-2016-8610 | 7 Debian, Fujitsu, Netapp and 4 more | 55 Debian Linux, M10-1, M10-1 Firmware and 52 more | 2025-04-20 | 7.5 High |
| A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients. | ||||
| CVE-2016-8743 | 4 Apache, Debian, Netapp and 1 more | 13 Http Server, Debian Linux, Clustered Data Ontap and 10 more | 2025-04-20 | 7.5 High |
| Apache HTTP Server, in all releases prior to 2.2.32 and 2.4.25, was liberal in the whitespace accepted from requests and sent in response lines and headers. Accepting these different behaviors represented a security concern when httpd participates in any chain of proxies or interacts with back-end application servers, either through mod_proxy or using conventional CGI mechanisms, and may result in request smuggling, response splitting and cache pollution. | ||||
| 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-2016-8740 | 2 Apache, Redhat | 3 Http Server, Jboss Core Services, Rhel Software Collections | 2025-04-12 | N/A |
| The mod_http2 module in the Apache HTTP Server 2.4.17 through 2.4.23, when the Protocols configuration includes h2 or h2c, does not restrict request-header length, which allows remote attackers to cause a denial of service (memory consumption) via crafted CONTINUATION frames in an HTTP/2 request. | ||||
| CVE-2014-3523 | 3 Apache, Microsoft, Redhat | 3 Http Server, Windows, Jboss Core Services | 2025-04-12 | N/A |
| Memory leak in the winnt_accept function in server/mpm/winnt/child.c in the WinNT MPM in the Apache HTTP Server 2.4.x before 2.4.10 on Windows, when the default AcceptFilter is enabled, allows remote attackers to cause a denial of service (memory consumption) via crafted requests. | ||||
| 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-2015-3185 | 4 Apache, Apple, Canonical and 1 more | 8 Http Server, Mac Os X, Mac Os X Server and 5 more | 2025-04-12 | N/A |
| The ap_some_auth_required function in server/request.c in the Apache HTTP Server 2.4.x before 2.4.14 does not consider that a Require directive may be associated with an authorization setting rather than an authentication setting, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging the presence of a module that relies on the 2.2 API behavior. | ||||
| 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-2016-7141 | 3 Haxx, Opensuse, Redhat | 5 Libcurl, Leap, Enterprise Linux and 2 more | 2025-04-12 | N/A |
| curl and libcurl before 7.50.2, when built with NSS and the libnsspem.so library is available at runtime, allow remote attackers to hijack the authentication of a TLS connection by leveraging reuse of a previously loaded client certificate from file for a connection for which no certificate has been set, a different vulnerability than CVE-2016-5420. | ||||
| 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. | ||||
