Summary

The astral-tokio-tar library up to version 0.5.3 contains a vulnerability that allows tar archives to extract outside of their intended destination directory when using the Entry::unpack_in_raw API. Additionally, the Entry::allow_external_symlinks control (default true) could be bypassed via a pair of symlinks that individually point within the destination but combine to point outside of it. These behaviors could be used to perform an arbitrary file write and potentially pivot into code execution.

Risk Assessment

An attacker with a malicious tar archive can write files outside the destination directory, potentially leading to overwriting critical system files or code execution in the application context.

Recommendation

Update the astral-tokio-tar library to version 0.5.4 or later, which includes a security fix. There is no other workaround.

Original NVD description (English source)

astral-tokio-tar is a tar archive reading/writing library for async Rust. In versions 0.5.3 and earlier of astral-tokio-tar, tar archives may extract outside of their intended destination directory when using the Entry::unpack_in_raw API. Additionally, the Entry::allow_external_symlinks control (which defaults to true) could be bypassed via a pair of symlinks that individually point within the destination but combine to point outside of it. These behaviors could be used individually or combined to bypass the intended security control of limiting extraction to the given directory. This in turn would allow an attacker with a malicious tar archive to perform an arbitrary file write and potentially pivot into code execution. This issue has been patched in version 0.5.4. There is no workaround other than upgrading.
