The issue occurs in the internal function responsible for converting cryptographic keys into serialized formats. During error handling, a memory structure is freed but not cleared, leading to a potential double free issue if an additional failure occurs later in the function. This condition may result in heap corruption or application instability in low-memory scenarios, posing a risk to system reliability where key export operations are performed."}, {"lang": "es", "value": "Se detect\u00f3 una falla en la funci\u00f3n de exportaci\u00f3n de claves de libssh. El problema se produce en la funci\u00f3n interna encargada de convertir las claves criptogr\u00e1ficas a formatos serializados. Durante la gesti\u00f3n de errores, se libera una estructura de memoria, pero no se borra, lo que puede provocar un problema de doble liberaci\u00f3n si se produce un fallo adicional m\u00e1s adelante en la funci\u00f3n.
