Amazon Linux AMI : rubygem-nokogiri (ALAS-2022-1648)

high Nessus Plugin ID 168617

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS-2022-1648 advisory.

 - 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. (CVE-2022-29181)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update rubygem-nokogiri' to update your system.
