IBM Business Automation Workflow and IBM BPM include a stand-alone tool for editing configuration properties files that is based on IBM SDK for Node.js. Vulnerability Details CVEID: CVE-2018-0732 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the sending of a very large prime value to the client by a malicious server during key agreement in a TLS handshake. By spending an unreasonably long period of time generating a key for this prime, a remote attacker could exploit this vulnerability to cause the client to hang. CVSS Base Score: 3.7 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 144658 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L) CVEID: CVE-2018-12115 DESCRIPTION: Node.js is vulnerable to a denial of service, caused by an out-of-bounds write in Buffer. An attacker could exploit this vulnerability to write to memory outside of a Buffer''s memory space, corrupt Buffer objects or cause the process to crash. CVSS Base Score: 8.2 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 148426 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:L/A:H) CVEID: CVE-2018-7166 DESCRIPTION: Node.js could allow a remote attacker to obtain sensitive information, caused by the return of uninitialized memory by the Buffer.alloc() function. By sending a specially crafted argument, an attacker could exploit this vulnerability to obtain sensitive information. CVSS Base Score: 7.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 148425 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) CVEID: CVE-2018-0737 DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive information, caused by a cache-timing side channel attack in the RSA Key generation algorithm. An attacker with access to mount cache timing attacks during the RSA key generation process could exploit this vulnerability to recover the private key and obtain sensitive information.
