Security Bulletin


Summary

IBM Sametime Community Server version 9 HF1 and version 9 Limited Use are affected by a vulnerability in OpenSSL (CVE-2014-0160) (a.k.a. Heartbleed vulnerability)

Vulnerability Details

CVE-ID: CVE-2014-0160

DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the TLS/DTLS heartbeat functionality. An attacker could exploit this vulnerability to expose 64k of private memory and retrieve secret keys. An attacker can repeatedly expose additional 64k chunks of memory. This vulnerability can be remotely exploited, authentication is not required and the exploit is not complex. An exploit can only partially affect the confidentially, but not integrity or availability.

CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/92322
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)

Warning: We strongly encourage you to take action as soon as possible as potential implications to your environment may be more serious than indicated by the CVSS score.

Affected Products and Versions

IBM Sametime Community Server version 9 HF1 and version 9 Limited Use (when TLS is enabled).

Note that TLS is not enabled by default.

Remediation/Fixes

Replace the relevant file based on your system


    Windows
      <Sametime_install_root>\STOpenSSL\ssleay32.dll

      For example: C:\Program Files\IBM\Domino\STOpenSSL\ssleay32.dll

    Linux
      <Sametime_install_root>/STOpenSSL/libssl.so.1.0.0

      For example: /opt/ibm/lotus/notes/latest/linux/STOpenSSL/libssl.so.1.0.0

    AIX
      <Sametime_install_root>/STOpenSSL/libssl.so.1.0.0

      For example: /opt/ibm/lotus/notes/latest/ibmpow/STOpenSSL/libssl.so.1.0.0

Instructions

  1. Unzip the dowloaded file.
  2. Stop the Sametime server.
  3. Rename the old file and copy the new one.
  4. Restart the Sametime server.

After applying the fix, additional instructions are needed for CVE-2014-0160 if TLS was enabled for the IBM Sametime Community Server version 9 HF1:

1. Replace your SSL Certificates.


    You need to revoke existing SSL certificates and reissue new certificates. You need to be sure not to generate the new certificates using the old private key and create a new private key (i.e. using "openssl genrsa") and use that new private key to create the new certificate signing request (CSR).

2. Reset User Credentials

    Users of network-facing applications protected by a vulnerable version of OpenSSL should be forced to reset their passwords and should revoke any authentication or session related cookies set prior to the time OpenSSL was upgraded and force the user to re-authenticate.

WARNING: Your environment may require additional fixes for other products, including non-IBM products. Please replace the SSL certificates and reset the user credentials after applying the necessary fixes to your environment.

Workarounds and Mitigations

None known if TLS is enabled for the product.
