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-2015-0205 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM 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-2014-3507 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
Memory leak in 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 zero-length DTLS fragments that trigger improper handling of the return value of a certain insert function.
CVE-2016-2177 3 Hp, Openssl, Oracle 6 Icewall Mcrp, Icewall Sso, Icewall Sso Agent Option and 3 more 2025-04-12 7.5 HIGH 9.8 CRITICAL
OpenSSL through 1.0.2h incorrectly uses pointer arithmetic for heap-buffer boundary checks, which might allow remote attackers to cause a denial of service (integer overflow and application crash) or possibly have unspecified other impact by leveraging unexpected malloc behavior, related to s3_srvr.c, ssl_sess.c, and t1_lib.c.
CVE-2016-0704 1 Openssl 1 Openssl 2025-04-12 4.3 MEDIUM 5.9 MEDIUM
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-2015-0286 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM 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-2015-0292 1 Openssl 1 Openssl 2025-04-12 7.5 HIGH N/A
Integer underflow in the EVP_DecodeUpdate function in crypto/evp/encode.c in the base64-decoding implementation in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted base64 data that triggers a buffer overflow.
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-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-2016-2107 8 Canonical, Debian, Google and 5 more 15 Ubuntu Linux, Debian Linux, Android and 12 more 2025-04-12 2.6 LOW 5.9 MEDIUM
The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-0169.
CVE-2015-0206 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM 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-2014-5139 1 Openssl 1 Openssl 2025-04-12 4.3 MEDIUM N/A
The ssl_set_client_disabled function in t1_lib.c in OpenSSL 1.0.1 before 1.0.1i allows remote SSL servers to cause a denial of service (NULL pointer dereference and client application crash) via a ServerHello message that includes an SRP ciphersuite without the required negotiation of that ciphersuite with the client.
CVE-2014-3511 1 Openssl 1 Openssl 2025-04-12 4.3 MEDIUM N/A
The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 1.0.1 before 1.0.1i allows man-in-the-middle attackers to force the use of TLS 1.0 by triggering ClientHello message fragmentation in communication between a client and server that both support later TLS versions, related to a "protocol downgrade" issue.
CVE-2014-3470 6 Fedoraproject, Mariadb, Openssl and 3 more 11 Fedora, Mariadb, Openssl and 8 more 2025-04-12 4.3 MEDIUM N/A
The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h, when an anonymous ECDH cipher suite is used, allows remote attackers to cause a denial of service (NULL pointer dereference and client crash) by triggering a NULL certificate value.
CVE-2014-3571 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted DTLS message that is processed with a different read operation for the handshake header than for the handshake body, related to the dtls1_get_record function in d1_pkt.c and the ssl3_read_n function in s3_pkt.c.
CVE-2014-0221 6 Fedoraproject, Mariadb, Openssl and 3 more 11 Fedora, Mariadb, Openssl and 8 more 2025-04-12 4.3 MEDIUM N/A
The dtls1_get_message_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 allows remote attackers to cause a denial of service (recursion and client crash) via a DTLS hello message in an invalid DTLS handshake.
CVE-2016-0705 5 Canonical, Debian, Google and 2 more 5 Ubuntu Linux, Debian Linux, Android and 2 more 2025-04-12 10.0 HIGH 9.8 CRITICAL
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-2014-3508 1 Openssl 1 Openssl 2025-04-12 4.3 MEDIUM N/A
The OBJ_obj2txt function in crypto/objects/obj_dat.c in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i, when pretty printing is used, does not ensure the presence of '\0' characters, which allows context-dependent attackers to obtain sensitive information from process stack memory by reading output from X509_name_oneline, X509_name_print_ex, and unspecified other functions.
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
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-2016-0799 2 Openssl, Pulsesecure 3 Openssl, Client, Steel Belted Radius 2025-04-12 10.0 HIGH 9.8 CRITICAL
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.
