Security Bulletin
Summary
IBM Security Network Intrusion Prevention System is affected by a problem related to the SSL implementation which, under very specific conditions, can cause CPU utilization to rapidly increase.
Vulnerability Details
CVE ID:
CVE-2014-0963
DESCRIPTION:
IBM Security Network Intrusion Prevention System is affected by a problem with the handling of certain SSL messages. The TLS implementation can, under very specific conditions, cause CPU utilization to rapidly increase. The situation occurs only in a certain error case that causes a single thread to begin looping. If this happens multiple times, more threads will begin to loop and an increase in CPU utilization will be seen. This increase could ultimately result in CPU exhaustion and unresponsiveness of the IBM Security Network Intrusion Prevention System and other software running on the affected system.
This issue can affect the availability of the system, but does not impact system confidentiality or integrity. This vulnerability can be remotely exploited, authentication is not required and the exploit is moderately complex.
To determine if your systems are being affected by this issue, you can monitor the CPU utilization for IBM Security Network Intrusion Prevention System instances.
