|---|---|---|---|---|
| CVE-2021-23840 | 8 Debian, Fujitsu, Mcafee and 5 more | 31 Debian Linux, M10-1, M10-1 Firmware and 28 more | 2026-04-16 | 7.5 High |
| Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. OpenSSL versions 1.0.2x and below are affected by this issue. However OpenSSL 1.0.2 is out of support and no longer receiving public updates. Premium support customers of OpenSSL 1.0.2 should upgrade to 1.0.2y. Other users should upgrade to 1.1.1j. Fixed in OpenSSL 1.1.1j (Affected 1.1.1-1.1.1i). Fixed in OpenSSL 1.0.2y (Affected 1.0.2-1.0.2x). | ||||
| CVE-2020-1968 | 5 Canonical, Debian, Fujitsu and 2 more | 25 Ubuntu Linux, Debian Linux, M10-1 and 22 more | 2026-04-16 | 3.7 Low |
| The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ciphersuites. This issue affects OpenSSL 1.0.2 which is out of support and no longer receiving public updates. OpenSSL 1.1.1 is not vulnerable to this issue. Fixed in OpenSSL 1.0.2w (Affected 1.0.2-1.0.2v). | ||||
| CVE-2004-0112 | 24 4d, Apple, Avaya and 21 more | 65 Webstar, Mac Os X, Mac Os X Server and 62 more | 2026-04-16 | N/A |
| The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read. | ||||
| CVE-2001-1141 | 2 Openssl, Ssleay | 2 Openssl, Ssleay | 2026-04-16 | N/A |
| The Pseudo-Random Number Generator (PRNG) in SSLeay and OpenSSL before 0.9.6b allows attackers to use the output of small PRNG requests to determine the internal state information, which could be used by attackers to predict future pseudo-random numbers. | ||||
| CVE-2003-0131 | 2 Openssl, Redhat | 4 Openssl, Enterprise Linux, Linux and 1 more | 2026-04-16 | N/A |
| The SSL and TLS components for OpenSSL 0.9.6i and earlier, 0.9.7, and 0.9.7a allow remote attackers to perform an unauthorized RSA private key operation via a modified Bleichenbacher attack that uses a large number of SSL or TLS connections using PKCS #1 v1.5 padding that cause OpenSSL to leak information regarding the relationship between ciphertext and the associated plaintext, aka the "Klima-Pokorny-Rosa attack." | ||||
| CVE-1999-0428 | 1 Openssl | 1 Openssl | 2026-04-16 | 6.5 Medium |
| OpenSSL and SSLeay allow remote attackers to reuse SSL sessions and bypass access controls. | ||||
| CVE-2006-4339 | 2 Openssl, Redhat | 4 Openssl, Enterprise Linux, Network Satellite and 1 more | 2026-04-16 | N/A |
| OpenSSL before 0.9.7, 0.9.7 before 0.9.7k, and 0.9.8 before 0.9.8c, when using an RSA key with exponent 3, removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents OpenSSL from correctly verifying X.509 and other certificates that use PKCS #1. | ||||
| CVE-2004-0975 | 4 Gentoo, Mandrakesoft, Openssl and 1 more | 6 Linux, Mandrake Linux, Mandrake Linux Corporate Server and 3 more | 2026-04-16 | N/A |
| The der_chop script in the openssl package in Trustix Secure Linux 1.5 through 2.1 and other operating systems allows local users to overwrite files via a symlink attack on temporary files. | ||||
| CVE-2002-0655 | 4 Apple, Openssl, Oracle and 1 more | 8 Mac Os X, Openssl, Application Server and 5 more | 2026-04-16 | N/A |
| OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, does not properly handle ASCII representations of integers on 64 bit platforms, which could allow attackers to cause a denial of service and possibly execute arbitrary code. | ||||
| CVE-2005-2946 | 2 Canonical, Openssl | 2 Ubuntu Linux, Openssl | 2026-04-16 | 7.5 High |
| The default configuration on OpenSSL before 0.9.8 uses MD5 for creating message digests instead of a more cryptographically strong algorithm, which makes it easier for remote attackers to forge certificates with a valid certificate authority signature. | ||||
| CVE-2003-0851 | 3 Cisco, Openssl, Redhat | 7 Css11000 Content Services Switch, Ios, Pix Firewall and 4 more | 2026-04-16 | N/A |
| OpenSSL 0.9.6k allows remote attackers to cause a denial of service (crash via large recursion) via malformed ASN.1 sequences. | ||||
| CVE-2004-0081 | 23 4d, Apple, Avaya and 20 more | 67 Webstar, Mac Os X, Mac Os X Server and 64 more | 2026-04-16 | N/A |
| OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool. | ||||
| CVE-2002-1568 | 2 Openssl, Redhat | 2 Openssl, Enterprise Linux | 2026-04-16 | N/A |
| OpenSSL 0.9.6e uses assertions when detecting buffer overflow attacks instead of less severe mechanisms, which allows remote attackers to cause a denial of service (crash) via certain messages that cause OpenSSL to abort from a failed assertion, as demonstrated using SSLv2 CLIENT_MASTER_KEY messages, which are not properly handled in s2_srvr.c. | ||||
| CVE-2002-0656 | 4 Apple, Openssl, Oracle and 1 more | 8 Mac Os X, Openssl, Application Server and 5 more | 2026-04-16 | N/A |
| Buffer overflows in OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, allow remote attackers to execute arbitrary code via (1) a large client master key in SSL2 or (2) a large session ID in SSL3. | ||||
| CVE-2005-1797 | 1 Openssl | 1 Openssl | 2026-04-16 | N/A |
| The design of Advanced Encryption Standard (AES), aka Rijndael, allows remote attackers to recover AES keys via timing attacks on S-box lookups, which are difficult to perform in constant time in AES implementations. | ||||
| CVE-2000-0535 | 2 Freebsd, Openssl | 2 Freebsd, Openssl | 2026-04-16 | N/A |
| OpenSSL 0.9.4 and OpenSSH for FreeBSD do not properly check for the existence of the /dev/random or /dev/urandom devices, which are absent on FreeBSD Alpha systems, which causes them to produce weak keys which may be more easily broken. | ||||
| CVE-2003-0545 | 2 Openssl, Redhat | 2 Openssl, Linux | 2026-04-16 | 9.8 Critical |
| Double free vulnerability in OpenSSL 0.9.7 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an SSL client certificate with a certain invalid ASN.1 encoding. | ||||
| CVE-2002-0657 | 1 Openssl | 1 Openssl | 2026-04-16 | N/A |
| Buffer overflow in OpenSSL 0.9.7 before 0.9.7-beta3, with Kerberos enabled, allows attackers to execute arbitrary code via a long master key. | ||||
| CVE-2003-0078 | 4 Freebsd, Openbsd, Openssl and 1 more | 6 Freebsd, Openbsd, Openssl and 3 more | 2026-04-16 | N/A |
| ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack." | ||||
| CVE-2002-0659 | 4 Apple, Openssl, Oracle and 1 more | 8 Mac Os X, Openssl, Application Server and 5 more | 2026-04-16 | N/A |
| The ASN1 library in OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, allows remote attackers to cause a denial of service via invalid encodings. | ||||
