Because of this, if a process crashed and was quickly replaced with a containerized one, apport could be made to forward the core dump to the container, potentially leaking sensitive information. `consistency_checks` is now being called before `_check_global_pid_and_forward`. Additionally, given that the PID-reuse race condition cannot be reliably detected from userspace alone, crashes are only forwarded to containers if the kernel provided a pidfd, or if the crashing process was unprivileged (i.e., if dump mode == 1)."}, {"lang": "es", "value": "La condici\u00f3n de ejecuci\u00f3n en Canonical Apport (hasta la versi\u00f3n 2.32.0 incluida) permite a un atacante local filtrar informaci\u00f3n confidencial mediante la reutilizaci\u00f3n de PID aprovechando los espacios de nombres. Al gestionar un fallo, la funci\u00f3n `_check_global_pid_and_forward`, que detecta si el proceso causante del fallo reside en un contenedor, se invocaba antes que `consistency_checks`, que intenta detectar si el proceso causante del fallo ha sido reemplazado. Por ello, si un proceso falla y se reemplaza r\u00e1pidamente por uno contenedorizado, se pod\u00eda ejecutar `apport` para reenviar el volcado de memoria al contenedor, lo que podr\u00eda filtrar informaci\u00f3n confidencial. `consistency_checks` ahora se invoca antes que `_check_global_pid_and_forward`. Adem\u00e1s, dado que la condici\u00f3n de ejecuci\u00f3n de reutilizaci\u00f3n de PID no se puede detectar de forma fiable solo desde el espacio de usuario, los fallos solo se reenv\u00edan a los contenedores si el n\u00facleo proporcion\u00f3 un pidfd o si el proceso causante del fallo no ten\u00eda privilegios (es decir, si el modo de volcado es 1)."}], "lastModified": "2025-08-22T19:36:15.910", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:canonical:apport:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "A2661E14-5C57-45A4-98B9-3ACBECBD57B9", "versionEndIncluding": "2.32.0"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:lts:*:*:*", "vulnerable": true, "matchCriteriaId": "F7016A2A-8365-4F1A-89A2-7A19F2BCAE5B"}, {"criteria": "cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*", "vulnerable": true, "matchCriteriaId": "23A7C53F-B80F-4E6A-AFA9-58EEA84BE11D"}, {"criteria": "cpe:2.3:o:canonical:ubuntu_linux:20.04:*:*:*:lts:*:*:*", "vulnerable": true, "matchCriteriaId": "902B8056-9E37-443B-8905-8AA93E2447FB"}, {"criteria": "cpe:2.3:o:canonical:ubuntu_linux:22.04:*:*:*:lts:*:*:*", "vulnerable": true, "matchCriteriaId": "359012F1-2C63-415A-88B8-6726A87830DE"}, {"criteria": "cpe:2.3:o:canonical:ubuntu_linux:24.04:*:*:*:lts:*:*:*", "vulnerable": true, "matchCriteriaId": "BF90B5A4-6E55-4369-B9D4-E7A061E797D2"}, {"criteria": "cpe:2.3:o:canonical:ubuntu_linux:24.10:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "DE07EF30-B50E-4054-9918-50EFA416073B"}, {"criteria": "cpe:2.3:o:canonical:ubuntu_linux:25.04:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E1AE2209-6CBC-4189-89ED-DA0FF100D77D"}], "operator": "OR"}]}], "sourceIdentifier": "security@ubuntu.com"}
