How to fix?

0.97-incubator users should upgrade to commons-imaging-1.0-alpha1.

Overview

org.apache.commons:commons-sanselan is a java image library for reading and writing a variety of image formats.

Affected versions of this package are vulnerable to Denial of Service (DoS). Certain input files parsed by the package could make the code hang if the Apache Sanselan 0.97-incubator Java image library is used in conjunction with the package to parse them.

Please note that Apache Sanselan (incubating) was renamed to Apache Commons Imaging and a fix version can be found in that package in commons-imaging-1.0-alpha1.

This vulnerability differs from CVE-2018-17202 where parsing of input files results in an infinite loop.

##Details 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 ws package
