Description of the vulnerability

The OpenSSL version 1.0.2i product fixed a bug in CRL management.

However, this fix does not check if a pointer is NULL, before using it.

An attacker can therefore force a NULL pointer to be dereferenced via a CRL on an application linked to OpenSSL 1.0.2i, in order to trigger a denial of service.

Description of the vulnerability

The OpenSSL version 1.1.0a product fixed the CVE-2016-6307 vulnerability.

However, the reception of a TLS message of 16kb frees a memory area before reusing it.

An attacker can therefore force the usage of a freed memory area via TLS on an application linked to OpenSSL 1.1.0a, in order to trigger a denial of service, and possibly to run code.

Description of the vulnerability

The OpenSSL library works on large numbers to perform operations such are RSA.

The BN_bn2dec() function converts a large number to its decimal representation. However, a special number forces BN_div_word() to return a limit value, then data are written after the end of the memory area.

An attacker can therefore generate a memory corruption via BN_bn2dec() of OpenSSL, in order to trigger a denial of service, and possibly to run code.

Description of the vulnerability

The OpenSSL library implements DTLS (Datagram Transport Layer Security, for example on UDP).

In order to manage replays, OpenSSL uses a sliding window containing accepted sequence numbers. However, if an attacker sends a packet with a large sequence number, the window is moved, and legitimate packets thus have numbers before the beginning of the window, and are rejected.

An attacker can therefore send a DTLS packet with a large sequence number to an application compiled with OpenSSL, in order to trigger a denial of service.

Description of the vulnerability

The OpenSSL library implements DTLS (Datagram Transport Layer Security, for example on UDP).

DTLS packets can be in the wrong order. OpenSSL has to keep them in memory, in order to reassemble them. However, in two cases, message queues are not cleared.

An attacker can therefore send DTLS packets in the wrong order with missing packets to an application compiled with OpenSSL, in order to trigger a denial of service.

Description of the vulnerability

The OpenSSL product implements the RFC 3161 Public Key Infrastructure Time-Stamp Protocol.

However, the TS_OBJ_print_bio() function tries to read a memory area located outside the expected range, which triggers a fatal error, or leads to the disclosure of a memory fragment.

An attacker can therefore force a read at an invalid address via TS_OBJ_print_bio() of OpenSSL, in order to trigger a denial of service, or to obtain sensitive information.

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.
