CVE-2016-0798 1 Openssl 1 Openssl 2025-04-12 7.8 HIGH 7.5 HIGH
Memory leak in the SRP_VBASE_get_by_user implementation 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 consumption) by providing an invalid username in a connection attempt, related to apps/s_server.c and crypto/srp/srp_vfy.c.
CVE-2015-3193 3 Canonical, Nodejs, Openssl 3 Ubuntu Linux, Node.js, Openssl 2025-04-12 5.0 MEDIUM 7.5 HIGH
The Montgomery squaring implementation in crypto/bn/asm/x86_64-mont5.pl in OpenSSL 1.0.2 before 1.0.2e on the x86_64 platform, as used by the BN_mod_exp function, mishandles carry propagation and produces incorrect output, which makes it easier for remote attackers to obtain sensitive private-key information via an attack against use of a (1) Diffie-Hellman (DH) or (2) Diffie-Hellman Ephemeral (DHE) ciphersuite.
CVE-2014-0195 4 Fedoraproject, Mariadb, Openssl and 1 more 5 Fedora, Mariadb, Openssl and 2 more 2025-04-12 6.8 MEDIUM 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-2015-1790 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
The PKCS7_dataDecodefunction in crypto/pkcs7/pk7_doit.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a PKCS#7 blob that uses ASN.1 encoding and lacks inner EncryptedContent data.
CVE-2016-0703 1 Openssl 1 Openssl 2025-04-12 4.3 MEDIUM 5.9 MEDIUM
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 accepts a nonzero CLIENT-MASTER-KEY CLEAR-KEY-LENGTH value for an arbitrary cipher, which allows man-in-the-middle attackers to determine the MASTER-KEY value and decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, a related issue to CVE-2016-0800.
CVE-2016-0702 4 Canonical, Debian, Nodejs and 1 more 4 Ubuntu Linux, Debian Linux, Node.js and 1 more 2025-04-12 1.9 LOW 5.1 MEDIUM
The MOD_EXP_CTIME_COPY_FROM_PREBUF function in crypto/bn/bn_exp.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g does not properly consider cache-bank access times during modular exponentiation, which makes it easier for local users to discover RSA keys by running a crafted application on the same Intel Sandy Bridge CPU core as a victim and leveraging cache-bank conflicts, aka a "CacheBleed" attack.
CVE-2016-0800 2 Openssl, Pulsesecure 3 Openssl, Client, Steel Belted Radius 2025-04-12 4.3 MEDIUM 5.9 MEDIUM
The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a ServerVerify message before establishing that a client possesses certain plaintext RSA data, which makes it easier for remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a "DROWN" attack.
CVE-2015-3194 4 Canonical, Debian, Nodejs and 1 more 4 Ubuntu Linux, Debian Linux, Node.js and 1 more 2025-04-12 5.0 MEDIUM 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-2015-0204 1 Openssl 1 Openssl 2025-04-12 4.3 MEDIUM 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-2015-0291 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
The sigalgs implementation in t1_lib.c in OpenSSL 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) by using an invalid signature_algorithms extension in the ClientHello message during a renegotiation.
CVE-2014-0198 6 Debian, Fedoraproject, Mariadb and 3 more 9 Debian Linux, Fedora, Mariadb and 6 more 2025-04-12 4.3 MEDIUM N/A
The do_ssl3_write function in s3_pkt.c in OpenSSL 1.x through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, does not properly manage a buffer pointer during certain recursive calls, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors that trigger an alert condition.
CVE-2015-3195 9 Apple, Canonical, Debian and 6 more 25 Mac Os X, Ubuntu Linux, Debian Linux and 22 more 2025-04-12 5.0 MEDIUM 5.3 MEDIUM

CVE-2016-2178 6 Canonical, Debian, Nodejs and 3 more 7 Ubuntu Linux, Debian Linux, Node.js and 4 more 2025-04-12 2.1 LOW 5.5 MEDIUM
The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack.
CVE-2014-3567 1 Openssl 1 Openssl 2025-04-12 7.1 HIGH N/A
Memory leak in the tls_decrypt_ticket function in t1_lib.c in OpenSSL before 0.9.8zc, 1.0.0 before 1.0.0o, and 1.0.1 before 1.0.1j allows remote attackers to cause a denial of service (memory consumption) via a crafted session ticket that triggers an integrity-check failure.
CVE-2016-6309 1 Openssl 1 Openssl 2025-04-12 10.0 HIGH 9.8 CRITICAL
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-2015-0285 1 Openssl 1 Openssl 2025-04-12 4.3 MEDIUM N/A
The ssl3_client_hello function in s3_clnt.c in OpenSSL 1.0.2 before 1.0.2a does not ensure that the PRNG is seeded before proceeding with a handshake, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by sniffing the network and then conducting a brute-force attack.
