Denial of Service (DoS)
Affecting github.com/minio/minio/cmd package
github.com/minio/minio/cmd is an open source object storage server compatible with Amazon S3 APIs.
Affected versions of the package are vulnerable to Denial of Service (DoS). The entire body of a request was read into memory to verify the content-md5 or content-sha56 checksum.
Denial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users.
Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime.
One popular Denial of Service vulnerability is DDoS (a Distributed Denial of Service), an attack that attempts to clog network pipes to the system by generating a large volume of traffic from many machines.
When it comes to open source libraries, DoS vulnerabilities allow attackers to trigger such a crash or crippling of the service by using a flaw either in the application code or from the use of open source libraries.
Two common types of DoS vulnerabilities:
High CPU/Memory Consumption- An attacker sending crafted requests that could cause the system to take a disproportionate amount of time to process. For example, commons-fileupload:commons-fileupload.
Crash - An attacker sending crafted requests that could cause the system to crash. For Example, npm
github.com/minio/minio/cmd to version 9c8b7306f55f2c8c0a5c7cea9a8db9d34be8faa7 or higher.
