Amazon Linux 2023 Security Advisory: ALAS2023-2026-2034
Advisory Released Date: 2026-08-04
Advisory Updated Date: 2026-08-04
Severity:
Important
Issue Overview:
rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.9.7 to before 0.10.79, X509Ref::ocsp_responders returns OCSP responder URLs from a certificate's AIA extension as OpensslString, whose Deref<Target = str> wraps the raw bytes with str::from_utf8_unchecked. OpenSSL does not enforce that the underlying IA5String is ASCII, so a certificate with non-UTF-8 bytes in its OCSP accessLocation causes safe Rust code to construct a &str that violates the UTF-8 invariant -- resulting in undefined behavior. This vulnerability is fixed in 0.10.79. (CVE-2026-42327)
Affected Packages:
