Security Bulletin: IBM PureApplication Service is affected by vulnerabilities (CVE-2018-3639, CVE-2018-3640)

Vulnerability Details

CVEID: CVE-2018-3639
DESCRIPTION: Multiple Intel CPU's could allow a local attacker to obtain sensitive information, caused by utilizing sequences of speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known. By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to bypass security restrictions and gain read access to privileged memory. Note: This vulnerability is the Speculative Store Bypass (SSB), also known as Variant 4 or "SpectreNG".
CVSS Base Score: 4.3

CVEID: CVE-2018-3640
DESCRIPTION: Multiple Intel CPU's could allow a local attacker to obtain sensitive information, caused by utilizing sequences of speculative execution that perform speculative reads of system registers. By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to determine the values stored in system registers. Note: This vulnerability is the Rogue System Register Read (RSRE), also known as Variant 3a.
