Уязвимость в функции "std::fs::remove_dir_all" в Rust, позволяющая удаление защищённых файлов через гонку условий
Описание
В стандартной библиотеке языка Rust (версии 1.0.0–1.58.0) обнаружена уязвимость в функции std::fs::remove_dir_all, связанная с состоянием гонки (CWE-363), позволяющей следовать за символическими ссылками. Злоумышленник может использовать эту уязвимость для обмана привилегированного приложения с целью удаления файлов и каталогов, к которым злоумышленник не имеет доступа.
Затронутые версии ПО
- Уязвимы версии Rust от 1.0.0 до 1.58.0
- Исправление доступно в версии Rust 1.58.1
Ограничения исправления
Целевые платформы macOS до версии 10.10 (Yosemite) и REDOX остаются уязвимыми из-за отсутствия доступных API для полной защиты от атаки.
Рекомендации
Особое внимание рекомендуется уделить обновлению, если программы запускаются в привилегированных контекстах, таких как системные демоны или исполняемые файлы с правами setuid, поскольку они имеют наибольший риск быть затронутыми.

Rust is a multi-paradigm, general-purpose programming language designed for performance and safety, especially safe concurrency. The Rust Security Response WG was notified that the `std::fs::remove_dir_all` standard library function is vulnerable a race condition enabling symlink following (CWE-363). An attacker could use this security issue to trick a privileged program into deleting files and directories the attacker couldn't otherwise access or delete. Rust 1.0.0 through Rust 1.58.0 is affected by this vulnerability with 1.58.1 containing a patch. Note that the following build targets don't have usable APIs to properly mitigate the attack, and are thus still vulnerable even with a patched toolchain: macOS before version 10.10 (Yosemite) and REDOX. We recommend everyone to update to Rust 1.58.1 as soon as possible, especially people developing programs expected to run in privileged contexts (including system daemons and setuid binaries), as those have the highest risk of being aff...
