Description of the vulnerability

The OpenSSL library disables by default SSLv2, excepted if the SSL_OP_NO_SSLv2 option is used.

SSLv2 cipher algorithms can be disabled on the server. However, a malicious client can still use these algorithms.

An attacker can therefore connect to a SSLv2 server with disabled ciphers in OpenSSL, in order to create a TLS session which is not secure.

OpenSSL: obtaining private exponent via DH Small Subgroups

Synthesis of the vulnerability

In some special configurations, an attacker can find the private DH exponent of the OpenSSL peer, in order to decrypt other sessions.

Description of the vulnerability

Since version 1.0.2, the OpenSSL library can generate DH unsafe parameters of style X9.42 (subgroup size "q"), to support the RFC 5114.

In this case, an attacker can find the private DH exponent of the peer, if the DH key is reused. The DH key is reused in the following cases:
 - SSL_CTX_set_tmp_dh() or SSL_set_tmp_dh() is used without the option SSL_OP_SINGLE_DH_USE set, which is rare.
 - SSL_CTX_set_tmp_dh_callback() or SSL_set_tmp_dh_callback() is used in an undocumented mode.
 - Static DH ciphersuites are used.

In some special configurations, an attacker can therefore find the private DH exponent of the OpenSSL peer, in order to decrypt other sessions.

Description of the vulnerability

The OpenSSH product implements a SSH client and server.

The SSH client contains an undocumented experimental feature named Roaming, which is implemented in the roaming_client.c file. This feature is enabled by default, and it is used to restart an old session. It is impacted by two vulnerabilities.

The Roaming feature can be used by a SSH server to read the SSH client memory, to obtain its keys. [severity:3/4; CVE-2016-0777]

The Roaming feature can be used by a SSH server to trigger an overflow and a descriptor leak in the SSH client, in order to generate a denial of service. [severity:2/4; CVE-2016-0778]

An attacker, who owns a malicious SSH server, can therefore invite a client to connect with OpenSSH, and then call the Roaming feature, in order to obtain sensitive information about keys used by the SSH client.

Description of the vulnerability

During the initialization of a TLS session, the client and the server negotiate cryptographic algorithms. The RC4 algorithm can be chosen to encrypt data.

For some weak keys (one over 2^24), the Invariance Weakness can be used to predict the two LSB (Least Significant Bit) of the 100 first bytes encrypted with RC4. The first TLS message is "Finished" (36 bytes), thus an attacker can predict LSBs of 64 bytes.

An attacker can therefore use the Bar Mitzvah Attack on TLS, in order to obtain sensitive information encrypted by RC4.

Description of the vulnerability

The TLS protocol uses a series of messages which have to be exchanged between the client and the server, before establishing a secured session.

Several cryptographic algorithms can be negotiated, such as algorithms allowed for USA export (less than 512 bits).

An attacker, located as a Man-in-the-Middle, can inject during the session initialization a message choosing an export algorithm. This message should generate an error, however some TLS clients accept it.

Note: the variant related to Windows is described in VIGILANCE-VUL-16332.

An attacker, located as a Man-in-the-Middle, can therefore force the Chrome, JSSE, LibReSSL, Mono or OpenSSL client to accept a weak export algorithm, in order to more easily capture or alter exchanged data.

Description of the vulnerability

An SSL/TLS session can be established using several protocols:
 - SSL 2.0 (obsolete)
 - SSL 3.0
 - TLS 1.0
 - TLS 1.1
 - TLS 1.2

An attacker can downgrade the version to SSLv3. However, with SSL 3.0, an attacker can change the padding position with a CBC encryption, in order to progressively guess clear text fragments.

This vulnerability is named POODLE (Padding Oracle On Downgraded Legacy Encryption).

An attacker, located as a Man-in-the-Middle, can therefore decrypt a SSL 3.0 session, in order to obtain sensitive information.

bash: code execution via Function Variable

Synthesis of the vulnerability

An attacker can define a special environment variable, which is transmitted (via CGI or OpenSSH for example) to bash, in order to execute code.

Description of the vulnerability

The bulletin VIGILANCE-VUL-15399 describes a vulnerability of bash.

However, the offered patch (VIGILANCE-SOL-36695) is incomplete. An variant of the initial attack can thus still be used to execute code or to create a file.

In this case, the code is run when the variable is parsed (which is not necessarily an environment variable), and not when the shell starts. The impact may thus be lower, but this was not confirmed.

An attacker can therefore define a special environment variable, which is transmitted (via CGI or OpenSSH for example) to bash, in order to execute code.
