openssl-1.0

The c_rehash script does not properly sanitise shell metacharacters to prevent command injection.  This script is distributed by some operating systems in a...

The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained...

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...

OpenSSL 1.0.2 supports SSLv2. If a client attempts to negotiate SSLv2 with a server that is configured to support both SSLv2 and more recent SSL and TLS...

A security issue has been found in OpenSSL before version 1.1.1l. ASN.1 strings are represented internally within OpenSSL as an ASN1_STRING structure which...

OpenSSL 1.0.2 will accept a certificate with explicitly set Basic Constraints to CA:FALSE as a valid CA if it is present in the trusted bundle.

A denial of service security issue was discovered in OpenSSL before 1.1.1i. The X.509 GeneralName type is a generic type for representing different types of...

A flaw was found in openssl in versions 1.0.2 to 1.0.2w. A Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able...

A padding oracle has been found in OpenSSL versions prior to 1.0.2r. This issue does not impact OpenSSL 1.1.1 or 1.1.0. If an application encounters a fatal...

A vulnerability has been found in the ECC scalar multiplication implementation of OpenSSL < 1.1.0i and <= 1.0.2p. The implementation, used in e.g. ECDSA and...

A cache-timing side channel attack in the RSA key generation algorithm has been found in OpenSSL <= 1.1.0h and <= 1.0.2o. An attacker with sufficient access...

A timing vulnerability has been found in DSA signature generation in openssl versions up to and including 1.1.1, where information is leaked via a side...

During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause...

There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. No EC algorithms are affected....

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...

A carry propagation bug has been found in OpenSSL < 1.1.0g in the x86_64 Montgomery squaring procedure. No EC algorithms are affected. Analysis suggests...

A security issue has been found in OpenSSL < 1.1.0g. If an X.509 certificate has a malformed IPAddressFamily extension, OpenSSL could do a one-byte buffer...
