  "title": "rust-rustix: Rustix is a set of safe Rust bindings to POSIX-ish APIs",
  "description": "Rustix is a set of safe Rust bindings to POSIX-ish APIs. When using \u0060rustix::fs::Dir\u0060 using the \u0060linux_raw\u0060 backend, it\u0027s possible for the iterator to \u0022get stuck\u0022 when an IO error is encountered. Combined with a memory over-allocation issue in \u0060rustix::fs::Dir::read_more\u0060, this can cause quick and unbounded memory explosion (gigabytes in a few seconds if used on a hot path) and eventually lead to an OOM crash of the application. The symptoms were initially discovered in https://github.com/imsnif/bandwhich/issues/284. That post has lots of details of our investigation. Full details can be read on the GHSA-c827-hfw6-qwvm repo advisory. If a program tries to access a directory with its file descriptor after the file has been unlinked (or any other action that leaves the \u0060Dir\u0060 iterator in the stuck state), and the implementation does not break after seeing an error, it can cause a memory explosion. As an example, Linux\u0027s various virtual file systems (e.g. \u0060/proc\u0060, \u0060/sys\u0060) can contain directories that spontaneously pop in and out of existence. Attempting to iterate over them using \u0060rustix::fs::Dir\u0060 directly or indirectly (e.g. with the \u0060procfs\u0060 crate) can trigger this fault condition if the implementation decides to continue on errors. An attacker knowledgeable about the implementation details of a vulnerable target can therefore try to trigger this fault condition via any one or a combination of several available APIs. If successful, the application host will quickly run out of memory, after which the application will likely be terminated by an OOM killer, leading to denial of service. This issue has been addressed in release versions 0.35.15, 0.36.16, 0.37.25, and 0.38.19. Users are advised to upgrade. There are no known workarounds for this issue.",
