(IBM Issues Fix for IBM Tivoli Provisioning Manager) OpenSSL Flaws Let Remote Users Deny Service and Decrypt TLS Sessions in Certain Cases
SecurityTracker Alert ID:  1035489
SecurityTracker URL:  http://securitytracker.com/id/1035489
CVE Reference:   CVE-2016-0702, CVE-2016-0705, CVE-2016-0797, CVE-2016-0798, CVE-2016-0799, CVE-2016-0800   (Links to External Site)
Date:  Apr 5 2016
Impact:   Denial of service via network, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 5.1.1, 7.1.1
Description:   Multiple vulnerabilities were reported in OpenSSL. A remote user can decrypt TLS sessions in certain cases. A remote user can cause denial of service conditions on the target system. IBM Tivoli Provisioning Manager is affected.

A remote user can decrypt TLS sessions in certain cases by using a server that supports SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle [CVE-2016-0800]. This attack is known as a DROWN attack.

Systems with a private key used on another server for any protocol that allows SSLv2 connections are affected.

Systems running versions prior to 1.0.2a, 1.0.1m, 1.0.0r, and 0.9.8zf (released on March 19, 2015) can be exploited more readily.

Nimrod Aviram, Sebastian Schinzel, Juraj Somorovsky, Nadia Heninger, Maik Dankel, Jens Steube, Luke Valenta, David Adrian, J. Alex Halderman, Viktor Dukhovni, Emilia Kasper, Shaanan Cohney, Susanne Engels, Christof Paar, and Yuval Shavitt reported this vulnerability.

A remote user can create a specially crafted private DSA key that, when processed by OpenSSL, will trigger a double free memory error and cause denial of service conditions [CVE-2016-0705].

Adam Langley (Google/BoringSSL) reported this vulnerability.

A remote user can supply a specially crafted username value to the target SRP server to trigger a memory leak [CVE-2016-0798].

Emilia Kasper of the OpenSSL development team reported this vulnerability.

A user can create specially crafted data (e.g., configuration file) that, when processed by OpenSSL, will trigger a null pointer dereference in the BN_hex2bn/BN_dec2bn() functions [CVE-2016-0797].

Guido Vranken reported this vulnerability.

A user can create specially crafted data that, when processed by OpenSSL, will trigger a memory error in BIO_*printf() functions [CVE-2016-0799].

Guido Vranken reported this vulnerability.

A local user can conduct a side-channel attack against a system based on the Intel Sandy-Bridge microarchitecture to potentially recover RSA keys [CVE-2016-0702].

Yuval Yarom, the University of Adelaide and NICTA, Daniel Genkin, Technion and Tel Aviv University, and Nadia Heninger, University of Pennsylvania, reported this vulnerability.

The SSLv2 's2_srvr.c' code does not ensure that a clear-key-length value is 0 for non-export ciphers. As a result, clear-key bytes can displace encrypted-key bytes, which can be exploited to conduct a key recovery attack [CVE-2016-0703].

Versions 1.0.2, 1.0.1l, 1.0.0q, and 0.9.8ze and prior versions are affected.

David Adrian and J. Alex Halderman of the University of Michigan reported this vulnerability.

The Bleichenbacher protection for export cipher suites in 's2_srvr.c' overwrites bytes incorrectly in the master-key, which may provide a Bleichenbacher oracle that can be used to decrypt sessions [CVE-2016-0704].

Versions 1.0.2, 1.0.1l, 1.0.0q, and 0.9.8ze and all prior versions are affected.

David Adrian and J. Alex Halderman of the University of Michigan reported this vulnerability.

A remote user can trigger an out-of-bounds memory write error in doapr_outch() in 'crypto/bio/b_print.c' to potentially execute arbitrary code on the target system [CVE-2016-2842].

Guido Vranken reported this vulnerability.

Impact:   A remote user can decrypt TLS sessions in certain cases.

A remote user can cause denial of service conditions.

A remote user can execute arbitrary code on the target system.

Solution:   IBM has issued a fix for CVE-2016-0702, CVE-2016-0705, CVE-2016-0797, CVE-2016-0798, CVE-2016-0799, and CVE-2016-0800 for IBM Tivoli Provisioning Manager for OS Deployment and IBM Tivoli Provisioning Manager for Images (5.1.1 build 051.07, 7.1.1.20 build 280.63).
