Description of the vulnerability

The OpenSSL product implements SSL/TLS, which uses a handshake.

However, by using a handshake with a ChangeCipherSpec message, an attacker can force the usage of weak keys.

An attacker can therefore act as a man in the middle between a client and a server using OpenSSL, in order to read or alter exchanged data.

Description of the vulnerability

A client based on the OpenSSL library can create an encrypted session using elliptic curves (ECDH : elliptic curves and Diffie-Hellman).

However, a malicious server can negotiate an Anonymous ECDH ciphersuite, in order to trigger a denial of service in the OpenSSL client.

An attacker, who is located on a TLS server, can therefore use Anonymous ECDH, in order to trigger a denial of service in OpenSSL client applications.

Description of the vulnerability

The ECDSA (Elliptic Curve Digital Signature Algorithm) algorithm uses a secret "k" value.

However, a local attacker can monitor the process linked to OpenSSL, and use the "FLUSH+RELOAD Cache" attack on a conditional branch (if), to obtain bit after bit the "k" secret value.

A local attacker can therefore guess the ECDSA secret used by the OpenSSL implementation, in order to obtain sensitive information.

Description of the vulnerability

The OpenSSL product uses a proprietary implementation of malloc to manage its memory.

However, when this feature is disabled with OPENSSL_NO_BUF_FREELIST, a memory area is not freed, and the ssl3_setup_read_buffer() function can, in multi-thread mode, reuse data from another SSL session.

An attacker can therefore establish a connection with a multi-threaded application linked to OpenSSL with OPENSSL_NO_BUF_FREELIST, in order to potentially inject data in the session of another user.

Description of the vulnerability

The SSL_set_mode() function of OpenSSL defines the behavior of the library. The SSL_MODE_RELEASE_BUFFERS parameter, added in version 1.0.0, indicates to free the memory as soon as it it not needed anymore. The SSL module of Apache httpd uses it when Apache is configured to save memory.

The do_ssl3_write() function of the ssl/s3_pkt.c file sends SSLv3 packets. After sending data, the memory can be freed if SSL_MODE_RELEASE_BUFFERS is used, so a pointer can be NULL. However, OpenSSL does not check if this pointer is NULL, before using it.

An attacker can therefore dereference a NULL pointer in OpenSSL applications using SSL_MODE_RELEASE_BUFFERS, in order to trigger a denial of service.

Description of the vulnerability

The DTLS (Datagram Transport Layer Security) protocol, based on TLS, provides a cryptographic layer over the UDP protocol.

However, if the size of data of a DTLS fragment is greater than the size of the storage array, an overflow occurs.

An attacker can therefore generate a buffer overflow via DTLS of OpenSSL, in order to trigger a denial of service, and possibly to execute code.

Description of the vulnerability

The OpenSSL product implements DTLS, which uses a handshake.

However, a special handshake triggers an infinite recursion in the OpenSSL client.

An attacker, who is located on a DTLS server, can therefore use a malicious handshake, in order to trigger a denial of service in OpenSSL client applications.

Description of the vulnerability

The Range header defined in the HTTP protocol indicates a byte range that server should return. For example, to obtain byte between 10 to 30 and 50 to 60:
  Range: bytes=10-30,50-60
The Request-Range header is the obsolete name of Range.

Apache processes the following objects:
 - bucket: an abstract storage area (memory, file, etc.).
 - brigade: a chained list of buckets

When Apache httpd receives a query containing the Range header, it stores each range in a brigade. However, if the range list is large, this brigade consumes a lot of memory.

An attacker can therefore use several parallel queries using Range or Request-Range, in order to progressively use the available memory.
