CVE-2016-2183 6 Cisco, Nodejs, Openssl and 3 more 9 Content Security Management Appliance, Node.js, Openssl and 6 more 2025-04-12 5.0 MEDIUM 7.5 HIGH
The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.
CVE-2014-3570 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
The BN_sqr implementation in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not properly calculate the square of a BIGNUM value, which might make it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors, related to crypto/bn/asm/mips.pl, crypto/bn/asm/x86_64-gcc.c, and crypto/bn/bn_asm.c.
CVE-2015-0290 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
The multi-block feature in the ssl3_write_bytes function in s3_pkt.c in OpenSSL 1.0.2 before 1.0.2a on 64-bit x86 platforms with AES NI support does not properly handle certain non-blocking I/O cases, which allows remote attackers to cause a denial of service (pointer corruption and application crash) via unspecified vectors.
CVE-2016-2106 2 Openssl, Redhat 8 Openssl, Enterprise Linux Desktop, Enterprise Linux Hpc Node and 5 more 2025-04-12 5.0 MEDIUM 7.5 HIGH
Integer overflow in the EVP_EncryptUpdate function in crypto/evp/evp_enc.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 data.
CVE-2016-6308 1 Openssl 1 Openssl 2025-04-12 7.1 HIGH 5.9 MEDIUM
statem/statem_dtls.c in the DTLS implementation in OpenSSL 1.1.0 before 1.1.0a allocates memory before checking for an excessive length, which might allow remote attackers to cause a denial of service (memory consumption) via crafted DTLS messages.
CVE-2014-3506 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM 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-2014-0076 1 Openssl 1 Openssl 2025-04-12 1.9 LOW 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-2015-1793 2 Openssl, Oracle 4 Openssl, Jd Edwards Enterpriseone Tools, Opus 10g Ethernet Switch Family and 1 more 2025-04-12 6.4 MEDIUM 6.5 MEDIUM
The X509_verify_cert function in crypto/x509/x509_vfy.c in OpenSSL 1.0.1n, 1.0.1o, 1.0.2b, and 1.0.2c does not properly process X.509 Basic Constraints cA values during identification of alternative certificate chains, which allows remote attackers to spoof a Certification Authority role and trigger unintended certificate verifications via a valid leaf certificate.
CVE-2015-0289 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
The PKCS#7 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 does not properly handle a lack of outer ContentInfo, which allows attackers to cause a denial of service (NULL pointer dereference and application crash) by leveraging an application that processes arbitrary PKCS#7 data and providing malformed data with ASN.1 encoding, related to crypto/pkcs7/pk7_doit.c and crypto/pkcs7/pk7_lib.c.
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-2014-8275 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 does not enforce certain constraints on certificate data, which allows remote attackers to defeat a fingerprint-based certificate-blacklist protection mechanism by including crafted data within a certificate's unsigned portion, related to crypto/asn1/a_verify.c, crypto/dsa/dsa_asn1.c, crypto/ecdsa/ecs_vrf.c, and crypto/x509/x_all.c.
CVE-2014-0224 9 Fedoraproject, Filezilla-project, Mariadb and 6 more 20 Fedora, Filezilla Server, Mariadb and 17 more 2025-04-12 5.8 MEDIUM 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-2015-3194 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-2016-2176 1 Openssl 1 Openssl 2025-04-12 6.4 MEDIUM 8.2 HIGH
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-2000-1254 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM 7.5 HIGH
crypto/rsa/rsa_gen.c in OpenSSL before 0.9.6 mishandles C bitwise-shift operations that exceed the size of an expression, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by leveraging improper RSA key generation on 64-bit HP-UX platforms.
CVE-2016-2842 1 Openssl 1 Openssl 2025-04-12 10.0 HIGH 9.8 CRITICAL
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-2015-0293 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
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 allows remote attackers to cause a denial of service (s2_lib.c assertion failure and daemon exit) via a crafted CLIENT-MASTER-KEY message.
CVE-2016-2181 2 Openssl, Oracle 2 Openssl, Linux 2025-04-12 5.0 MEDIUM 7.5 HIGH
The Anti-Replay feature in the DTLS implementation in OpenSSL before 1.1.0 mishandles early use of a new epoch number in conjunction with a large sequence number, which allows remote attackers to cause a denial of service (false-positive packet drops) via spoofed DTLS records, related to rec_layer_d1.c and ssl3_record.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-2016-0701 1 Openssl 1 Openssl 2025-04-12 2.6 LOW 3.7 LOW
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.
