Abstract
Security vulnerabilities have been discovered in OpenSSL.
Content
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. It
can be exploited on any system (ie. server, client, agent)
receiving connections using the vulnerable OpenSSL library.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/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.
CVE-ID: CVE-2014-0076
DESCRIPTION: OpenSSL could allow a local attacker to obtain
sensitive information, caused by an implementation error in ECDSA
(Elliptic Curve Digital Signature Algorithm). An attacker could
exploit this vulnerability using the FLUSH+RELOAD cache
side-channel attack to recover ECDSA nonces. This vulnerability can
only be exploited locally, authentication is not required and the
exploit is not complex.
CVSS Base Score: 2.1
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91990
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:L/Au:N/C:P/I:N/A:N)
Affected products and versions
- IBM ToolsCenter Suite versions 9.41, 9.50, and 9.51
- IBM Advanced Settings Utility (ASU)
- IBM Dynamic System Analysis (DSA)
- IBM UpdateXpress System Packs Installer (UXSPI)
Remediation:
IBM recommends updating to version IBM ToolsCenter Suite version 9.52.
After applying the fix, additional instructions are needed for CVE-2014-0160
- 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 (ie using "openssl genrsa") and use that new private key to create the new certificate signing request (CSR). - 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.
