CVE-2018-1000538

Name of the Vulnerable Software and Affected Versions Minio S3 server versions prior to RELEASE.2018-05-16T23-35-33Z

Description The issue is related to an Allocation of Memory Without Limits or Throttling in the write-to-RAM functionality, which can result in a Denial of Service. This can be exploited by sending V4-(pre)signed requests with large bodies.

Recommendations For versions prior to RELEASE.2018-05-16T23-35-33Z, consider updating to a version that includes the fix committed after 9c8b7306f55f2c8c0a5c7cea9a8db9d34be8faa7 to resolve the issue. As a temporary workaround, consider restricting the size of requests or limiting the use of V4-(pre)signed requests to minimize the risk of exploitation.
