http://security.gentoo.org/

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"
