Computer vulnerabilities of Red Hat JBoss Enterprise Application Platform

computer vulnerability alert CVE-2016-2141

JGroups: unauthorized joining of a group

Synthesis of the vulnerability

An attacker can join a protected communication group managed with JGroups, in order to listen to sensitive communications.
Impacted products: JGroups, Junos Space, JBoss EAP by Red Hat.
Severity: 4/4.
Consequences: data reading, data creation/edition, data flow.
Provenance: intranet client.
Creation date: 24/06/2016.
Identifiers: CVE-2016-2141, JSA10838, RHSA-2016:1328-01, RHSA-2016:1329-01, RHSA-2016:1330-01, RHSA-2016:1331-01, RHSA-2016:1332-01, RHSA-2016:1333-01, RHSA-2016:1334-01, RHSA-2016:1345-01, RHSA-2016:1346-01, RHSA-2016:1347-01, RHSA-2016:1374-01, RHSA-2016:1389-01, RHSA-2016:1432-01, RHSA-2016:1433-01, RHSA-2016:1434-01, RHSA-2016:1435-01, RHSA-2016:2035-01, VIGILANCE-VUL-19966.

Description of the vulnerability

The JGroups product manages communication groups which may be cryptographically protected.

However, authentication checks are incomplete and key management is wrong. An unauthorized attacker can get the encryption keys and join the group both for sending and receiving.

An attacker can therefore join a protected communication group managed with JGroups, in order to listen to sensitive communications.

Description of the vulnerability

The Apache Tomcat product uses a slightly fork of the Apache Commons FileUpload library.

This library is used to receive files from an HTTP client to the server. However, when the file size is such that the size of the MIME envelope (file content + MIME headers) is equal to the size of the file reading buffer, the transfer requires an extremely long duration.

An attacker can therefore send files of a specially chosen size to Apache Tomcat, in order to overload the server.

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

Several vulnerabilities were announced in OpenSSL.

An attacker can act as a Man-in-the-Middle and use the AES CBC algorithm with a server supporting AES-NI, in order to read or write data in the session. This vulnerability was initially fixed in versions 1.0.1o and 1.0.2c, but it was not disclosed at that time. [severity:3/4; CVE-2016-2108]

An attacker can act as a Man-in-the-Middle and use the AES CBC algorithm with a server supporting AES-NI, in order to read or write data in the session. [severity:3/4; CVE-2016-2107]

An attacker can generate a buffer overflow in EVP_EncodeUpdate(), which is mainly used by command line applications, in order to trigger a denial of service, and possibly to run code. [severity:2/4; CVE-2016-2105]

An attacker can generate a buffer overflow in EVP_EncryptUpdate(), which is difficult to reach, in order to trigger a denial of service, and possibly to run code. [severity:2/4; CVE-2016-2106]

An attacker can trigger an excessive memory usage in d2i_CMS_bio(), in order to trigger a denial of service. [severity:2/4; CVE-2016-2109]

An attacker can force a read at an invalid address in applications using X509_NAME_oneline(), in order to trigger a denial of service, or to obtain sensitive information. [severity:2/4; CVE-2016-2176]

Description of the vulnerability

Several vulnerabilities were announced in OpenSSL.

An attacker can act as a Man-in-the-Middle on a server supporting SSLv2 and EXPORT ciphers (this configuration is considered as weak since several years), in order to read or write data in the session. [severity:2/4; CVE-2016-0800, VU#583776]

An attacker can force the usage of a freed memory area when OpenSSL processes a DSA private key (this scenario is rare), in order to trigger a denial of service, and possibly to run code. [severity:2/4; CVE-2016-0705]

An attacker can read a memory fragment via SRP_VBASE_get_by_user, in order to obtain sensitive information. [severity:1/4; CVE-2016-0798]

An attacker can force a NULL pointer to be dereferenced in BN_hex2bn(), in order to trigger a denial of service. [severity:1/4; CVE-2016-0797]

An attacker can use a very large string (size INT_MAX), to generate a memory corruption in the BIO_*printf() functions, in order to trigger a denial of service, and possibly to run code. [severity:2/4; CVE-2016-0799]

An attacker can use cache conflicts on Intel Sandy-Bridge, in order to obtain RSA keys. [severity:1/4; CVE-2016-0702]

An attacker can use a very large string (size INT_MAX), to generate a memory corruption in the internal doapr_outch() function, in order to trigger a denial of service, and possibly to run code. [severity:2/4; CVE-2016-2842]

Apache Tomcat: directory traversal of ServletContext

Synthesis of the vulnerability

An attacker, who is allowed to upload a malicious web application on the service, can traverse directories in ServletContext of Apache Tomcat, in order to read the content of a directory outside the service root path.
Impacted products: Tomcat, Debian, BIG-IP Hardware, TMOS, HP-UX, QRadar SIEM, Tivoli Directory Server, Junos Space, Snap Creator Framework, openSUSE Leap, Oracle Communications, Solaris, RHEL, JBoss EAP by Red Hat, SUSE Linux Enterprise Desktop, SLES, Ubuntu.
Severity: 2/4.
Consequences: data reading.
Provenance: document.

Description of the vulnerability

The Apache Tomcat product can execute a web application from an untrusted source with a Security Manager.

However, the getResource(), getResourceAsStream() and getResourcePaths() methods of ServletContext insert user's data directly in an access path. Sequences such as "/.." can thus be used by the web application to go in the upper directory.

An attacker, who is allowed to upload a malicious web application on the service, can therefore traverse directories in ServletContext of Apache Tomcat, in order to read the content of a directory outside the service root path.

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.

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.
