Hi, The following vulnerability was published for rust-tar. CVE-2026-33055[0]: | tar-rs is a tar archive reading/writing library for Rust. Versions | 0.4.44 and below have conditional logic that skips the PAX size | header in cases where the base header size is nonzero. As part of | CVE-2025-62518, the astral-tokio-tar project was changed to | correctly honor PAX size headers in the case where it was different | from the base header. This is almost the inverse of the astral- | tokio-tar issue. Any discrepancy in how tar parsers honor file size | can be used to create archives that appear differently when unpacked | by different archivers. In this case, the tar-rs (Rust tar) crate is | an outlier in checking for the header size - other tar parsers | (including e.g. Go archive/tar) unconditionally use the PAX size | override. This can affect anything that uses the tar crate to parse | archives and expects to have a consistent view with other parsers. | This issue has been fixed in version 0.4.45. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
