CVE-2022-0315

Rank-file disclosure or tampering via insecure temporary path

Published Mar 24, 2022 · Updated Aug 2, 2024

Insecure temporary-file creation in Horovod before 0.24.0 allows local users to read or alter an LSF jsrun rank file. The generate_jsrun_rankfile function calls tempfile.mktemp(), then opens the returned path separately, leaving a race in which another process can claim or redirect it. Exposure requires an LSF job using jsrun without binding_args; MPI, Gloo, Spark, and Ray runs are unaffected.
