Описание
Nokogiri is an open source XML and HTML library for Ruby. Nokogiri prior to version 1.13.6 does not type-check all inputs into the XML and HTML4 SAX parsers, allowing specially crafted untrusted inputs to cause illegal memory access errors (segfault) or reads from unrelated memory. Version 1.13.6 contains a patch for this issue. As a workaround, ensure the untrusted input is a String by calling #to_s or equivalent.
A flaw was found in the rubygem-nokogiri package. This flaw allows malicious users to change partial contents or configurations on the system. Additionally, this vulnerability can also cause a limited denial of service in the form of interruptions in resource availability.
Отчет
Red Hat Satellite 6.12 and later versions are not affected by this flaw.
Меры по смягчению последствий
To avoid this vulnerability in affected applications, ensure the untrusted input is a String by calling #to_s or equivalent.
