IBM Spectrum Scale is previously known as General Parallel File System (GPFS). Vulnerability Details CVEID: CVE-2018-1431 DESCRIPTION: A vulnerability in GSKit affects IBM Spectrum Scale that could allow a local attacker to obtain control of the Spectrum Scale daemon and to access and modify files in the Spectrum Scale file system, and possibly to obtain administrator privileges on the node. CVSS Base Score: 7.4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/139240 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) CVEID: CVE-2018-1447 DESCRIPTION: The GSKit CMS KDB logic fails to salt the hash function resulting in weaker than expected protection of passwords. A weak password may be recovered. Note: After update the customer should change password to ensure the new password is stored more securely. Products should encourage customers to take this step as a high priority action. CVSS Base Score: 5.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/139972 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N) CVEID: CVE-2017-3732 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a carry propagating bug in the x86_64 Montgomery squaring procedure. 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-2016-0705 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a double-free error when parsing DSA private keys. An attacker could exploit this vulnerability to corrupt memory and cause a denial of service. CVSS Base Score: 3.7 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111140 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) Affected Products and Versions All fix pack levels of IBM Db2 V10.5, and V11.1 editions on all Unix-type platforms are affected. Windows platforms are not affected. Remediation/Fixes Customers running any vulnerable fixpack level of an affected Program, V10.5 and V11.1, can contact IBM technical support to obtain the Spectrum Scale security package update. Before installing the Spectrum Scale security package, the DB2 level might need to be upgraded to the level that includes the supported Spectrum Scale level.
