vulnerability announce CVE-2015-4991

IBM SPSS Modeler: information disclosure via a memory dump

Synthesis of the vulnerability

A local attacker can read a memory fragment of IBM SPSS Modeler, in order to obtain sensitive information.
Impacted products: SPSS Modeler.
Severity: 2/4.
Consequences: data reading.
Provenance: document.
Creation date: 16/02/2016.
Identifiers: 1975663, CVE-2015-4991, VIGILANCE-VUL-18952.

Description of the vulnerability

The IBM SPSS Modeler product can save memory dumps.

However, the memory image includes some potentially sensitive information. The nature of these data, the retrieval complexity and the access conditions to these dumps are unknown.

A local attacker can therefore read a memory fragment of IBM SPSS Modeler, in order to obtain sensitive information.

vulnerability CVE-2015-7420 CVE-2015-7421

GSKit: two vulnerabilities of GDA

Synthesis of the vulnerability

An attacker can use several vulnerabilities of GSKit of IBM Tivoli Directory Server, Security Directory Server.
Impacted products: Security Directory Server, SPSS Modeler, Tivoli Workload Scheduler, WebSphere MQ.
Severity: 1/4.
Consequences: data reading, data creation/edition.
Provenance: internet client.
Number of vulnerabilities in this bulletin: 2.
Creation date: 26/01/2016.
Identifiers: 1978182, 1982432, 1983690, CVE-2015-7420, CVE-2015-7421, T1023277, VIGILANCE-VUL-18820.

Description of the vulnerability

The GSKit component provides a pseudo random number generator.

In order to keep the PRNG output unpredictable, the PRNG internal state must be unpredictable, uncopyable and never restored. However, a user program can create child processes with the fork() system call that duplicates the whole virtual memory of the calling process. So the child processes starts with the same state than their parent and so may produce the same pseudo-random sequence.

The internal state of the GSKit PRNG is so duplicated. [severity:1/4; CVE-2015-7420]

The internal state of the "ICC PRNG" of GSKit is so duplicated. [severity:1/4; CVE-2015-7421]

Description of the vulnerability

The Apache Commons Collections library is used by several Java applications.

A Java Gadgets ("gadget chains") object can contain Transformers, with an "exec" string containing a shell command which is run with the Java.lang.Runtime.exec() method. When raw data are unserialized, the readObject() method is thus called to rebuild the Gadgets object, and it uses InvokerTransformer, which runs the indicated shell command.

It can be noted that other classes (CloneTransformer, ForClosure, InstantiateFactory, InstantiateTransformer, PrototypeCloneFactory, PrototypeSerializationFactory, WhileClosure) also execute a shell command from raw data to deserialize.

However, several applications publicly expose (before authentication) the Java unserialization feature.

An attacker can therefore send a malicious serialized Gadget Chain object to a Java application using Apache Commons Collections, in order to run shell code.

Description of the vulnerability

The Diffie-Hellman algorithm is used to exchange cryptographic keys. The DHE_EXPORT suite uses prime numbers smaller than 512 bits.

The Diffie-Hellman algorithm is used by TLS. However, during the negotiation, an attacker, located as a Man-in-the-Middle, can force TLS to use DHE_EXPORT (event if stronger suites are available).

This vulnerability can then be combined with VIGILANCE-VUL-16951.

An attacker, located as a Man-in-the-Middle, can therefore force the TLS client/server to accept a weak export algorithm, in order to more easily capture or alter exchanged data.
