Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DLA-3149-1)
Summary:	The remote host is missing an update for the Debian 'ruby-nokogiri' package(s) announced via the DLA-3149-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'ruby-nokogiri' package(s) announced via the DLA-3149-1 advisory. Vulnerability Insight: Multiple vulnerabilities were discovered in Nokogiri, an HTML/XML/SAX/Reader parser for the Ruby programming language, leading to command injection, XML external entity injection (XXE), and denial-of-service (DoS). CVE-2019-5477 A command injection vulnerability allows commands to be executed in a subprocess via Ruby's `Kernel.open` method. Processes are vulnerable only if the undocumented method `Nokogiri::CSS::Tokenizer#load_file` is being called with unsafe user input as the filename. This vulnerability appears in code generated by the Rexical gem versions v1.0.6 and earlier. Rexical is used by Nokogiri to generate lexical scanner code for parsing CSS queries. CVE-2020-26247 XXE vulnerability: XML Schemas parsed by Nokogiri::XML::Schema are trusted by default, allowing external resources to be accessed over the network, potentially enabling XXE or SSRF attacks. This behavior is counter to the security policy followed by Nokogiri maintainers, which is to treat all input as untrusted by default whenever possible. CVE-2022-24836 Nokogiri contains an inefficient regular expression that is susceptible to excessive backtracking when attempting to detect encoding in HTML documents. For Debian 10 buster, these problems have been fixed in version 1.10.0+dfsg1-2+deb10u1. We recommend that you upgrade your ruby-nokogiri packages.
