Security Bulletin: IBM b-type Network/Storage switches is affected by Open Source OpenSSL Vulnerabilities (OpenSSL and Node.JS consumers).

Summary

IBM b-type Network/Storage switches has addressed the following vulnerabilities (CVE-2017-3730, CVE-2017-3731, CVE-2017-3732, CVE-2016-7055).

Vulnerability Details

CVEID:CVE-2017-3730**
DESCRIPTION: *OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference. By sending specially crafted parameters for a DHE or ECDHE key exchange, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/121311 for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
**
CVEID: CVE-2017-3731
DESCRIPTION: *OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds read when using a specific cipher. By sending specially crafted truncated packets, a remote attacker could exploit this vulnerability using CHACHA20/POLY1305 to cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/121312 for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
**
CVEID: CVE-2017-3732
DESCRIPTION: *OpenSSL could allow a remote attacker to obtain sensitive information, caused by a propagation error in the BN_mod_exp() function. An attacker could exploit this vulnerability to obtain information about the private key.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/121313 for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
**
CVEID: CVE-2016-7055
DESCRIPTION: *OpenSSL is vulnerable to a denial of service, caused by an error in a Broadwell-specific Montgomery multiplication procedure. By sending specially crafted data, a remote attacker could exploit this vulnerability to trigger errors in public-key operations in configurations where multiple remote clients select an affected EC algorithm and cause a denial of service.
CVSS Base Score: 5.3
