(IBM Issues Fix for IBM Tivoli Netcool System Service Monitor) OpenSSL Bugs Let Remote Users Deny Service and Potentially Execute Arbitrary Code
SecurityTracker Alert ID:  1033761
SecurityTracker URL:  http://securitytracker.com/id/1033761
CVE Reference:   CVE-2015-1788   (Links to External Site)
Date:  Oct 8 2015
Impact:   Denial of service via network, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 4.0
Description:   Multiple vulnerabilities were reported in OpenSSL. A remote user can cause denial of service conditions on the target system. A remote authenticated user may be able to execute arbitrary code on the target system. IBM Tivoli Netcool System Service Monitor is affected.

A remote authenticated user can send specially crafted application data to a connected DTLS peer between the ChangeCipherSpec and Finished messages to trigger an invalid memory free and cause a segmentation fault or memory corruption error and potentially execute arbitrary code [CVE-2014-8176]. Versions 0.9.8 prior to 0.9.8za, 1.0.0 prior to 1.0.0m, and 1.0.1 prior to 1.0.1h are affected.

Praveen Kariyanahalli and Ivan Fratric and Felix Groebert of Google separately reported this vulnerability.

A remote user can send specially crafted ECParameters to cause the target service to enter an infinite loop [CVE-2015-1788]. Applications that process public keys, certificate requests, or certificates are affected. TLS clients and TLS servers with client authentication enabled are affected. Versions 1.0.1 and 1.0.2 are affected.

Joseph Birr-Pixton reported this vulnerability on April 6, 2015.

A remote user can create a specially crafted certificate or certificate revocation list (CRL) that, when processed by the target application, will trigger an out-of-bound memory read in X509_cmp_time() and cause a segmentation fault [CVE-2015-1789]. TLS clients that verify CRLs are affected. TLS clients and servers with client authentication enabled and that use custom verification callbacks may be affected.

Robert Swiecki of Google reported this vulnerability on April 8, 2015 and Hanno Bock independently reported this vulnerability on April 11, 2015.

A remote user can create specially crafted ASN.1-encoded PKCS#7 data with a missing EnvelopedContent component to trigger a null pointer dereference [CVE-2015-1790]. Applications that decrypt or parse PKCS#7 data from untrusted sources are affected. OpenSSL clients and servers are not affected. The impact was not specified.

Michal Zalewski of Google reported this vulnerability on April 18, 2015.

A remote user can create a specially crafted signedData message that specifies an unknown hash function OID to trigger an infinite loop in the CMS code [CVE-2015-1792]. Applications that verify signedData messages using the CMS code are affected.

Johannes Bauer reported this vulnerability on March 31, 2015.

Impact:   A remote user can cause the target application to crash or enter an infinite loop.

A remote authenticated user may be able to execute arbitrary code on the target system.

The impact of one vulnerability was not disclosed.

Solution:   IBM has issued a fix for CVE-2015-1788 for IBM Tivoli Netcool System Service Monitor.
