This flaw allows an attacker to force a SUID process to crash and replace it with a non-SUID binary to access the original's privileged process coredump, allowing the attacker to read sensitive data, such as /etc/shadow content, loaded by the original process.\n\nA SUID binary or process has a special type of permission, which allows the process to run with the file owner's permissions, regardless of the user executing the binary. This allows the process to access more restricted data than unprivileged users or processes would be able to. An attacker can leverage this flaw by forcing a SUID process to crash and force the Linux kernel to recycle the process PID before systemd-coredump can analyze the /proc/pid/auxv file. If the attacker wins the race condition, they gain access to the original's SUID process coredump file. They can read sensitive content loaded into memory by the original binary, affecting data confidentiality."}, {"lang": "es", "value": "Se ha encontrado una vulnerabilidad en systemd-coredump. Este fallo permite a un atacante forzar un proceso SUID para que deje de funcionar y reemplazarlo con un no-SUID binario para acceder al proceso original y con privilegios coredump; lo que permite al atacante leer informaci\u00f3n sensible, como el contenido de /etc/shadow, cargado por el proceso original. Un binario SUID o proceso tiene un tipo especial de permiso que faculta al proceso a ejecutarse con los permisos del propietario del fichero, independientemente de qui\u00e9n sea el usuario que ejecuta el binario. Esto permite al proceso acceder a datos m\u00e1s restringidos que a un usuario sin privilegios o a un proceso. Un atacante puede aprovechar este fallo forzando la ca\u00edda de un proceso SUID y haciendo que el kernel de Linux recicle el PID del proceso antes de que systemd-coredump pueda analizar el fichero /proc/pid/auxv. Si el atacante gana la condici\u00f3n de carrera, obtiene acceso al fichero coredump del proceso SUID original y puede leer contenido sensible cargado en la memoria por el binario original, lo que afecta a la confidencialidad de la informaci\u00f3n."}], "lastModified": "2025-08-27T17:16:21.220", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:systemd_project:systemd:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "98671AC8-0605-4881-ADCC-2E10DE1AE90F", "versionEndExcluding": "252.37"}, {"criteria": "cpe:2.3:a:systemd_project:systemd:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "0E7F2C6F-96E2-4891-87CB-6077FC9605ED", "versionEndExcluding": "253.32", "versionStartIncluding": "253"}, {"criteria": "cpe:2.3:a:systemd_project:systemd:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C81ED4A1-39A0-4001-BB70-41F3D0CB127B", "versionEndExcluding": "254.25", "versionStartIncluding": "254"}, {"criteria": "cpe:2.3:a:systemd_project:systemd:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B946E172-E883-483C-8679-090E08FF83A8", "versionEndExcluding": "255.19", "versionStartIncluding": "255"}, {"criteria": "cpe:2.3:a:systemd_project:systemd:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "99646749-054D-4901-98D4-E2BFA9C2A650", "versionEndExcluding": "256.14", "versionStartIncluding": "256"}, {"criteria": "cpe:2.3:a:systemd_project:systemd:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C60BC789-E25D-4726-BCD0-6F28BC69579A", "versionEndExcluding": "257.6", "versionStartIncluding": "257"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:redhat:openshift_container_platform:4.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "932D137F-528B-4526-9A89-CD59FA1AB0FE"}, {"criteria": "cpe:2.3:o:redhat:enterprise_linux:7.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "142AD0DD-4CF3-4D74-9442-459CE3347E3A"}, {"criteria": "cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F4CFF558-3C47-480D-A2F0-BABF26042943"}, {"criteria": "cpe:2.3:o:redhat:enterprise_linux:9.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "7F6FB57C-2BC7-487C-96DD-132683AEB35D"}, {"criteria": "cpe:2.3:o:redhat:enterprise_linux:10.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D65C2163-CFC2-4ABB-8F4E-CB09CEBD006C"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:debian:debian_linux:11.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "FA6FEEC2-9F11-4643-8827-749718254FED"}, {"criteria": "cpe:2.3:o:debian:debian_linux:12.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "46D69DCC-AE4D-4EA5-861C-D60951444C6C"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:oracle:linux:8:-:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "CA9021D6-6027-42E9-A12D-7EA32C5C63F1"}, {"criteria": "cpe:2.3:o:oracle:linux:9:-:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "9E6116DA-D643-4C6D-8B90-0A41125F1EF0"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "FAB7877E-481F-42D2-9C30-AB2522E8F55C", "versionEndExcluding": "6.16"}], "operator": "OR"}]}], "sourceIdentifier": "secalert@redhat.com"}
