Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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 relies on the presence of the package as reported by the vendor.

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7659-1 advisory.

    It was discovered Nokogiri did not correctly parse XML Schemas. If a user or automated system were tricked     into opening a specially crafted file, an attacker could possibly use this issue to execute arbitrary     code. This issue only affected Ubuntu 20.04 LTS. (CVE-2020-26247)

    Agustin Gianni discovered that Nokogiri did not correctly parse XML and HTML files. If a user or automated     system were tricked into opening a specially crafted file, an attacker could possibly use this issue to     cause a denial of service or leak sensitive information. (CVE-2022-29181)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4015-1 advisory.

  - Nokogiri is an open source XML and HTML library for Ruby. Nokogiri `< v1.13.4` contains an inefficient     regular expression that is susceptible to excessive backtracking when attempting to detect encoding in     HTML documents.

The remote host is affected by the vulnerability described in GLSA-202208-29 (Nokogiri: Multiple Vulnerabilities)

  - Nokogiri is a Rubygem providing HTML, XML, SAX, and Reader parsers with XPath and CSS selector support. In     Nokogiri before version 1.11.0.rc4 there is an 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. This is fixed     in Nokogiri version 1.11.0.rc4. (CVE-2020-26247)
