However, if the type of the tensor is not an integral type, the operation crashes the Python interpreter as it tries to write to the memory area. If the file is too small, TensorFlow properly returns an error as the memory area has fewer bytes than what is needed for the tensor it creates. However, as soon as there are enough bytes, the above snippet causes a segmentation fault. This is because the allocator used to return the buffer data is not marked as returning an opaque handle since the needed virtual method is not overridden. This is fixed in versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and 2.4.0."}, {"lang": "es", "value": "En las versiones afectadas de TensorFlow, la operaci\u00f3n tf.raw_ops.ImmutableConst devuelve un tensor constante creado a partir de un archivo mapeado en memoria que se asume inmutable. Sin embargo, si el tipo de tensor no es un tipo integral, la operaci\u00f3n bloquea el int\u00e9rprete de Python cuando intenta escribir en el \u00e1rea de la memoria. Si el archivo es muy peque\u00f1o, TensorFlow devuelve apropiadamente un error ya que el \u00e1rea de la memoria posee menos bytes de los necesarios para el tensor que crea. Sin embargo, tan pronto como haya suficientes bytes, el fragmento anterior causa un fallo de segmentaci\u00f3n. Esto es debido a que el asignador usado para devolver los datos del b\u00fafer no est\u00e1 marcado como devolviendo un identificador opaco, ya que el m\u00e9todo virtual necesario no se anula. Esto es corregido en las versiones 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2 y 2.4.0."}], "lastModified": "2024-11-21T05:19:42.640", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "CA3A54AC-E0F8-4741-8A80-04EEF746B14B", "versionEndExcluding": "1.15.5"}, {"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "989E4548-7823-436F-A9FE-04158ED41C48", "versionEndExcluding": "2.0.4", "versionStartIncluding": "2.0.0"}, {"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "46417CA8-E666-4E12-B2A8-BB0E97D49BF4", "versionEndExcluding": "2.1.3", "versionStartIncluding": "2.1.0"}, {"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "57B24744-0D81-41E9-9ED0-7296368DEF00", "versionEndExcluding": "2.2.2", "versionStartIncluding": "2.2.0"}, {"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "DBEA56AF-3495-4883-9721-0FA9F08E7F6D", "versionEndExcluding": "2.3.2", "versionStartIncluding": "2.3.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
