Ap\u00f3s mais de quatro anos desde o \u00faltimo lan\u00e7amento, foi publicada a vers\u00e3o do pacote NTFS-3G 2021.8.22, que inclui um driver livre que opera no espa\u00e7o do usu\u00e1rio utilizando o mecanismo FUSE, e um conjunto de utilit\u00e1rios ntfsprogs para manipula\u00e7\u00e3o de parti\u00e7\u00f5es NTFS. O c\u00f3digo do projeto \u00e9 distribu\u00eddo sob a licen\u00e7a GPLv2. <\/p>\n<\/p>\n
O driver suporta leitura e grava\u00e7\u00e3o de dados em parti\u00e7\u00f5es NTFS e pode operar em uma ampla gama de sistemas operacionais que suportam FUSE, incluindo Linux, Android, macOS, FreeBSD, NetBSD, OpenBSD, Solaris, QNX e Haiku. A implementa\u00e7\u00e3o do sistema de arquivos NTFS fornecido pelo driver \u00e9 totalmente compat\u00edvel com os sistemas operacionais Windows XP, Windows Server 2003, Windows 2000, Windows Vista, Windows Server 2008, Windows 7, Windows 8 e Windows 10. O conjunto de utilit\u00e1rios ntfsprogs permite realizar opera\u00e7\u00f5es como cria\u00e7\u00e3o de parti\u00e7\u00f5es NTFS, verifica\u00e7\u00e3o de integridade, clonagem, redimensionamento e recupera\u00e7\u00e3o de arquivos exclu\u00eddos. Componentes gerais para operar com NTFS, utilizados no driver e nos utilit\u00e1rios, foram extra\u00eddos para uma biblioteca separada. <\/p>\n
A vers\u00e3o \u00e9 not\u00e1vel pela corre\u00e7\u00e3o de 21 vulnerabilidades. As vulnerabilidades s\u00e3o causadas por estouros de buffer ao processar diversos metadados e permitem a execu\u00e7\u00e3o de c\u00f3digo ao montar uma imagem NTFS especialmente formatada (incluindo a possibilidade de ataque ao conectar um dispositivo externo n\u00e3o verificado). Se o atacante tiver acesso local ao sistema onde o execut\u00e1vel ntfs-3g est\u00e1 instalado com a flag setuid root, as vulnerabilidades tamb\u00e9m podem ser utilizadas para elevar suas permiss\u00f5es. <\/p>\n
Entre as mudan\u00e7as n\u00e3o relacionadas \u00e0 seguran\u00e7a, destaca-se a unifica\u00e7\u00e3o das bases de c\u00f3digo das edi\u00e7\u00f5es est\u00e1vel e avan\u00e7ada do NTFS-3G, al\u00e9m da transfer\u00eancia do desenvolvimento do projeto para o GitHub. A nova vers\u00e3o tamb\u00e9m inclui corre\u00e7\u00f5es de erros acumulados e resolve problemas de compila\u00e7\u00e3o com vers\u00f5es antigas do libfuse. Os desenvolvedores realizaram uma an\u00e1lise das reclama\u00e7\u00f5es sobre o baixo desempenho do NTFS-3G. A an\u00e1lise mostrou que os problemas de desempenho est\u00e3o geralmente relacionados \u00e0 entrega de vers\u00f5es desatualizadas do projeto nos pacotes ou ao uso de configura\u00e7\u00f5es padr\u00e3o inadequadas (montagem sem a op\u00e7\u00e3o «big_writes», sem a qual a velocidade de transfer\u00eancia de arquivos \u00e9 reduzida em 3-4 vezes). De acordo com os testes realizados pela equipe de desenvolvedores, o desempenho do NTFS-3G \u00e9 apenas 15-20% inferior ao do ext4. \u0421\u043f\u0443\u0441\u0442\u044f \u0431\u043e\u043b\u0435\u0435
