GLSA 202006-05: Nokogiri: Command injection

Severity:normal
Title:Nokogiri: Command injection
Date:06/13/2020
Bugs: #691974
ID:202006-05

Synopsis

Nokogiri has a vulnerability allowing arbitrary execution of code if a certain function is used.

Background

Nokogiri is an HTML, XML, SAX, and Reader parser.

Affected packages

Package Vulnerable Unaffected Architecture(s)
dev-ruby/nokogiri < 1.10.4 >= 1.10.4 All supported architectures

Description

A command injection vulnerability in Nokogiri allows commands to be executed in a subprocess by Ruby’s Kernel.open method. Processes are vulnerable only if the undocumented method Nokogiri::CSS::Tokenizer#load_file is being passed untrusted user input.

Impact

A remote attacker could possibly execute arbitrary code with the privileges of the process.

Workaround

Avoid calling the undocumented method Nokogiri::CSS::Tokenizer#load_file with untrusted user input.

Resolution

All Nokogiri users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-ruby/nokogiri-1.10.4"
