Lodash versions 0.3.1 and 0.3.2 represent early iterations of this popular JavaScript utility library, designed as a performant and feature-rich alternative to Underscore.js. Both versions share the same core description: a drop-in replacement for Underscore, aiming to improve speed, fix bugs, and offer extended functionality. Key features like the absence of declared dependencies, development dependencies, and optional dependencies reflect the library's lightweight nature at this stage. Both versions are linked to the same GitHub repository, indicating common origins and a continuous development process. Both are crafted by John-David Dalton.
The significant difference lies in their release dates: version 0.3.2 was released on June 14, 2012, subsequent to version 0.3.1, released on June 11, 2012. This immediate succession suggests that version 0.3.2 likely includes minor bug fixes or incremental improvements over its predecessor. For developers using Lodash, opting for the newer version (0.3.2) is generally advisable, as it should incorporate the latest stability and performance enhancements available at that time. The tarball URLs in the dist attribute provide access to the specific archived versions of the library for download and integration into projects. Developers considering these versions should acknowledge their age and explore more recent Lodash releases for expanded functionality and broader community support.
All the vulnerabilities related to the version 0.3.2 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.
