From 0.5 to 0.5.17, local attacker can exploit a buffer overflow vulnerability in munged (the MUNGE authentication daemon) to leak cryptographic key material from process memory. With the leaked key material, the attacker could forge arbitrary MUNGE credentials to impersonate any user (including root) to services that rely on MUNGE for authentication. The vulnerability allows a buffer overflow by sending a crafted message with an oversized address length field, corrupting munged's internal state and enabling extraction of the MAC subkey used for credential verification. This vulnerability is fixed in 0.5.18."},{"lang":"es","value":"MUNGE es un servicio de autenticación para crear y validar credenciales de usuario. Desde 0.5 hasta 0.5.17, un atacante local puede explotar una vulnerabilidad de desbordamiento de búfer en munged (el demonio de autenticación de MUNGE) para filtrar material de clave criptográfica de la memoria del proceso. Con el material de clave filtrado, el atacante podría falsificar credenciales MUNGE arbitrarias para suplantar a cualquier usuario (incluido root) a servicios que dependen de MUNGE para la autenticación. La vulnerabilidad permite un desbordamiento de búfer al enviar un mensaje manipulado con un campo de longitud de dirección sobredimensionado, corrompiendo el estado interno de munged y permitiendo la extracción de la subclave MAC utilizada para la verificación de credenciales. Esta vulnerabilidad se corrige en 0.5.18."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:L","baseScore":7.7,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"LOW"},"exploitabilityScore":1.1,"impactScore":6.0},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":7.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":5.9}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-787"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:opensuse:munge:*:*:*:*:*:*:*:*","versionStartIncluding":"0.5","versionEndExcluding":"0.5.18","matchCriteriaId":"8FA863EF-F766-4A77-8313-1AFC05928932"}]}]},{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:debian:debian_linux:11.0:*:*:*:*:*:*:*","matchCriteriaId":"FA6FEEC2-9F11-4643-8827-749718254FED"}]}]}],"references":[{"url":"https://github.com/dun/munge/commit/bf40cc27c4ce8451d4b062c9de0b67ec40894812","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/dun/munge/releases/tag/munge-0.5.18","source":"security-advisories@github.com","tags":["Product","Release Notes"]},{"url":"https://github.com/dun/munge/security/advisories/GHSA-r9cr-jf4v-75gh","source":"security-advisories@github.com","tags":["Mitigation","Patch","Vendor Advisory"]},{"url":"http://www.openwall.com/lists/oss-security/2026/02/10/3","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mailing List","Patch","Third Party Advisory"]},{"url":"http://www.openwall.com/lists/oss-security/2026/02/17/6","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mailing List","Third Party Advisory"]},{"url":"https://lists.debian.org/debian-lts-announce/2026/02/msg00015.html","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mailing List","Third Party Advisory"]}]}}]}
