Description of the vulnerability

The source code of OpenSSL includes many loops where a pointer is used to go through a buffer.

The definition of the C language allows a pointer to be off by one byte after the buffer, but the behavior of any further access is undefined. Several end of loop tests follows the forme "pointer + current data length > end pointer" in such a way that these 2 expressions are not always defined according to the language specification. An attacker which can control dynamic memory allocations can trigger evaluation of undefined conditions and perhaps invalid memory access.

An attacker can therefore force a memory access at an invalid address in OpenSSL, in order to trigger a denial of service, or to obtain sensitive information.

Description of the vulnerability

OpenSSL includes an implementation of the DSA algorithm.

The BN_FLG_CONSTTIME flag requires this operation to be performed in constant time, in order to block attacks watching the process. However, the dsa_sign_setup() function of the lib/libssl/src/crypto/dsa/dsa_ossl.c file does not correctly initialize the BN_FLG_CONSTTIME flag.

An attacker can therefore monitor a process performing a DSA signature with OpenSSL, in order to potentially obtain information about the secret key.

Description of the vulnerability

The glibc library implements a DNS resolver (libresolv).

An application can thus call the getaddrinfo() function, which queries DNS servers. When the AF_UNSPEC type is used in the getaddrinfo() call, two DNS A and AAAA queries are sent simultaneously. However, this special case, and a case with AF_INET6 are not correctly managed, and lead to an overflow if the reply coming from the DNS server is larger than 2048 bytes.

An attacker, who owns a malicious DNS server, can therefore reply with large data to a client application using the getaddrinfo() function of the glibc, in order to trigger a denial of service, and possibly to run code in the client application.

Description of the vulnerability

The OpenSSL library implements TLS with the anonymous DH ciphersuite.

However, if the TLS server sends a ServerKeyExchange message with a value of p parameter set to zero, a fatal error occurs in the client linked to OpenSSL.

An attacker can therefore send a malicious ServerKeyExchange message to a client compiled with OpenSSL, in order to trigger a denial of service.

Description of the vulnerability

The OpenSSL library can be used by a multi-threaded client.

However, in this case, the SSL_CTX structure does not contain an updated PSK Identify Hint. OpenSSL can thus free twice the same memory area.

An attacker can therefore force the usage of a freed memory area via PSK Identify Hint of an OpenSSL multi-threaded client, in order to trigger a denial of service, and possibly to run code.

Description of the vulnerability

The OpenSSL library supports the PKCS#7 and CMS formats.

However, if an X509_ATTRIBUTE structure is malformed, OpenSSL does not initialize a memory area before returning it to the user reading PKCS#7 or CMS data.

It can be noted that SSL/TLS is not impacted.

An attacker can therefore read a memory fragment via X509_ATTRIBUTE of OpenSSL processing PKCS#7 or CMS data, in order to obtain sensitive information.

Description of the vulnerability

The OpenSSL library can use the RSA PSS algorithm to check the validity of X.509 certificates.

However, if the "mask generation" parameter is missing during the verification of a signature in ASN.1 format, OpenSSL does not check if a pointer is NULL, before using it.

An attacker can therefore force a NULL pointer to be dereferenced during the certificate verification of OpenSSL (in client or server mode), in order to trigger a denial of service.

Description of the vulnerability

The OpenSSL library uses the BN_mod_exp() function to perform a modular exponentiation on large numbers.

However, on an x86_64 processor, the BN_mod_exp() function can generate an incorrect result during the Montgomery Squaring procedure.

An attacker, with a significant amount of resources, can therefore attack the DH algorithm, in some OpenSSL usages, in order to compute the private key.
