Summary

ruby_parser allows local users to overwrite arbitrary files via symlink attack on temporary file with predictable name

The diff_pp function in lib/gauntlet_rubyparser.rb in the ruby_parser gem 3.1.1 and earlier for Ruby allows local users to overwrite arbitrary files via a symlink attack on a temporary file with a predictable name in /tmp.

ruby_parser → 3.1.2 (rubygems)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions

  1. What is CVE-2013-0162? CVE-2013-0162 is a low-severity security vulnerability in ruby_parser (rubygems), affecting versions >= 2.0.2, < 3.1.2. It is fixed in 3.1.2.
  2. Which versions of ruby_parser are affected by CVE-2013-0162? ruby_parser (rubygems) versions >= 2.0.2, < 3.1.2 is affected.
  3. Is there a fix for CVE-2013-0162? Yes. CVE-2013-0162 is fixed in 3.1.2. Upgrade to this version or later.
  4. Is CVE-2013-0162 exploitable, and should I be worried? Whether CVE-2013-0162 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

  5. What actually determines whether CVE-2013-0162 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
  6. How do I fix CVE-2013-0162? Upgrade ruby_parser to 3.1.2 or later.
