Microsoft fixes critical RCE bug in hcsshim library

May 4, 2018

Microsoft Corporation on Wednesday updated its Windows Host Compute Service Shim (hcsshim) library to correct a critical remote code execution bug caused by improper input validation when importing a container image.

In order to exploit the vulnerability -- designated CVE-2018-8115, "an attacker would place malicious code in a specially crafted container image which, if an authenticated administrator imported (pulled), could cause a container management service utilizing the Host Compute Service Shim library to execute malicious code on the Windows host," a Microsoft advisory states.
