Descriptions

An incomplete string comparison in the numpy.core component in NumPy before 1.22.0 allows attackers to trigger slightly incorrect copying by constructing specific string objects. NOTE: the vendor states that this reported code behavior is "completely harmless."

Una comparación incompleta de cadenas en el componente numpy.core en NumPy en versiones anteriores a la 1.22.0, permite a los atacantes activar una copia ligeramente incorrecta mediante la construcción de objetos de cadena específicos. NOTA: el proveedor afirma que este comportamiento de código reportado es "completamente inofensivo".

It was discovered that NumPy did not properly manage memory when specifying arrays of large dimensions. If a user were tricked into running malicious Python file, an attacker could cause a denial of service. This issue only affected Ubuntu 20.04 LTS. It was discovered that NumPy did not properly perform string comparison operations under certain circumstances.
