Summary
PowerKVM is affected by vulnerabilities in icoutils. IBM has now addressed these vulnerabilities.
Vulnerability Details
CVEID: CVE-2017-5208
DESCRIPTION: icoutils could allow a local attacker to execute arbitrary code on the system, caused by an integer overflow in the wrestool program. By creating a specially crafted executable and reading it via wrestool, an attacker could exploit this vulnerability to corrupt memory and execute arbitrary code on the system.
CVSS Base Score: 8.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/125733 for the current score
CVSS Environmental Score*: Undefined
