Version Details and Security Vulnerabilities

Versions 4.3.1 and earlier of semver are affected by a regular expression denial of service vulnerability when extremely long version strings are parsed.

Recommendation

Update to version 4.3.2 or later

Versions of the package semver before 7.5.2 on the 7.x branch, before 6.3.1 on the 6.x branch, and all other versions before 5.7.2 are vulnerable to Regular Expression Denial of Service (ReDoS) via the function new Range, when untrusted user data is provided as a range.

PhantomJS through 2.1.1 has an arbitrary file read vulnerability, as demonstrated by an XMLHttpRequest for a file:// URI. The vulnerability exists in the page.open() function of the webpage module, which loads a specified URL and calls a given callback. An attacker can supply a specially crafted HTML file, as user input, that allows reading arbitrary files on the filesystem. For example, if page.render() is the function callback, this generates a PDF or an image of the targeted file. NOTE: this product is no longer developed.

Versions of fstream prior to 1.0.12 are vulnerable to Arbitrary File Overwrite. Extracting tarballs containing a hardlink to a file that already exists in the system and a file that matches the hardlink will overwrite the system's file with the contents of the extracted file. The fstream.DirWriter() function is vulnerable.

Recommendation

Upgrade to version 1.0.12 or later.
