Lodash versions 0.3.0 and 0.3.1 represent incremental advancements in a utility library designed as a drop-in replacement for Underscore.js, offering performance enhancements, bug fixes, and extended functionality. For developers considering adoption, it's crucial to understand the evolution between these closely released versions.
Both versions share a common foundation, promising improved speed and robustness compared to Underscore.js. However, version 0.3.1, released shortly after 0.3.0, likely incorporates targeted fixes and optimizations discovered after the initial 0.3.0 release. While the descriptions remain identical, emphasizing the overarching goals of performance and feature enrichment, developers benefit from understanding that version 0.3.1 implicitly offers increased stability and potentially finer-tuned performance characteristics.
The core offering remains consistent: a rich suite of functions that simplify common JavaScript tasks, targeting improved code readability, maintainability and speed. By leveraging Lodash, developers can abstract away complex logic and ensure cross-browser compatibility, allowing them to focus on application-specific features.The author and repository information point to a strong commitment to the library's development and maintenance. The release dates show that the project was actively maintained and that new iterations were expected. Although specifics regarding code differences in the release aren't clear from the data, developers are most likely served by using the newer release.
All the vulnerabilities related to the version 0.3.1 of the package
Prototype Pollution in lodash
Versions of lodash before 4.17.12 are vulnerable to Prototype Pollution. The function defaultsDeep allows a malicious user to modify the prototype of Object via {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.17.12 or later.
Prototype Pollution in lodash
Versions of lodash before 4.17.5 are vulnerable to prototype pollution.
The vulnerable functions are 'defaultsDeep', 'merge', and 'mergeWith' which allow a malicious user to modify the prototype of Object via __proto__ causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.17.5 or later.
Prototype Pollution in lodash
Versions of lodash before 4.17.11 are vulnerable to prototype pollution.
The vulnerable functions are 'defaultsDeep', 'merge', and 'mergeWith' which allow a malicious user to modify the prototype of Object via {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.17.11 or later.
Regular Expression Denial of Service (ReDoS) in lodash
lodash prior to 4.7.11 is affected by: CWE-400: Uncontrolled Resource Consumption. The impact is: Denial of service. The component is: Date handler. The attack vector is: Attacker provides very long strings, which the library attempts to match using a regular expression. The fixed version is: 4.7.11.
Regular Expression Denial of Service (ReDoS) in lodash
All versions of package lodash prior to 4.17.21 are vulnerable to Regular Expression Denial of Service (ReDoS) via the toNumber, trim and trimEnd functions.
Steps to reproduce (provided by reporter Liyuan Chen):
var lo = require('lodash');
function build_blank(n) {
var ret = "1"
for (var i = 0; i < n; i++) {
ret += " "
}
return ret + "1";
}
var s = build_blank(50000) var time0 = Date.now();
lo.trim(s)
var time_cost0 = Date.now() - time0;
console.log("time_cost0: " + time_cost0);
var time1 = Date.now();
lo.toNumber(s) var time_cost1 = Date.now() - time1;
console.log("time_cost1: " + time_cost1);
var time2 = Date.now();
lo.trimEnd(s);
var time_cost2 = Date.now() - time2;
console.log("time_cost2: " + time_cost2);
Command Injection in lodash
lodash versions prior to 4.17.21 are vulnerable to Command Injection via the template function.
