Summary
IBM Tivoli Monitoring 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 Tivoli Monitoring 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 Tivoli Monitoring 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 Tivoli Monitoring components.
CVSS Base Score: 7.1

current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:C)
CVE-ID: CVE-2014-0076
DESCRIPTION: An attacker running a program on the same machine as where the
victim is running a program could use CPU timing information to discover key
information about certain kinds of binary type Elliptic Curves used in Digital
signatures during signing operations. Although GSKit only generates Prime type
Elliptic Curves, externally generated keys may be imported in GSKit.
