Nokogiri `1.13.8` and `1.13.9` fail to check the return value from `xmlTextReaderExpand` in the method `Nokogiri::XML::Reader#attribute_hash`. This can lead to a null pointer exception when invalid markup is being parsed. For applications using `XML::Reader` to parse untrusted inputs, this may potentially be a vector for a denial of service attack. Users are advised to upgrade to Nokogiri `>= 1.13.10`. Users may be able to search their code for calls to either `XML::Reader#attributes` or `XML::Reader#attribute_hash` to determine if they are affected."},{"lang":"es","value":"Nokogiri es una librería XML y HTML de código abierto para el lenguaje de programación Ruby. Nokogiri `1.13.8` y `1.13.9` no pueden verificar el valor de retorno de `xmlTextReaderExpand` en el método `Nokogiri::XML::Reader#attribute_hash`. Esto puede provocar una excepción de puntero null cuando se analiza un marcado no válido. Para las aplicaciones que utilizan `XML::Reader` para analizar entradas que no son de confianza, esto puede ser potencialmente un vector para un ataque de Denegación de Servicio (DoS). Se recomienda a los usuarios actualizar a Nokogiri `>= 1.13.10`. Los usuarios pueden buscar en su código llamadas a `XML::Reader#attributes` o `XML::Reader#attribute_hash` para determinar si están afectados."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-252"},{"lang":"en","value":"CWE-476"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:nokogiri:nokogiri:1.13.8:*:*:*:*:ruby:*:*","matchCriteriaId":"5B720209-2ADC-4B12-8BEE-D5F827279B06"},{"vulnerable":true,"criteria":"cpe:2.3:a:nokogiri:nokogiri:1.13.9:*:*:*:*:ruby:*:*","matchCriteriaId":"AA8BBC8F-F780-4359-81CA-EBB3A5767FB5"}]}]}],"references":[{"url":"https://github.com/sparklemotion/nokogiri/commit/85410e38410f670cbbc8c5b00d07b843caee88ce","source":"security-advisories@github.com","tags":["Patch","Third Party Advisory"]},{"url":"https://github.com/sparklemotion/nokogiri/commit/9fe0761c47c0d4270d1a5220cfd25de080350d50","source":"security-advisories@github.com","tags":["Patch","Third Party Advisory"]},{"url":"https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-qv4q-mr5r-qprj","source":"security-advisories@github.com","tags":["Third Party Advisory"]},{"url":"https://github.com/sparklemotion/nokogiri/commit/85410e38410f670cbbc8c5b00d07b843caee88ce","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch","Third Party Advisory"]},{"url":"https://github.com/sparklemotion/nokogiri/commit/9fe0761c47c0d4270d1a5220cfd25de080350d50","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch","Third Party Advisory"]},{"url":"https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-qv4q-mr5r-qprj","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]}]}}]}
