Amazon Linux 2 : rust, --advisory ALAS2-2026-3246 (ALAS-2026-3246)

The version of rust installed on the remote host is prior to 1.94.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3246 advisory. A flaw in the gix-date library can generate invalid non-UTF8 strings, leading to undefined behavior when processed. The most...

CVE-2026-33055 tar-rs incorrectly ignores PAX size headers if header size is nonzero

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...
