Out-of-bounds Read Vulnerability in Eclipse Foundation NetX Duo

Short explanation

An out-of-bounds read vulnerability exists in Eclipse Foundation NetX Duo due to a missing tlv_length check in _nx_secure_x509_parse_signature_data.

Why does it matter?

Remote, unauthenticated attackers can trigger a denial of service condition during the TLS handshake using specially crafted certificates.

What should be done?

  • Follow vendor advisories
  • Review updates for unaffected versions

NetX Duo, _nx_secure_x509_parse_signature_data fonksiyonunda tlv_length değerini kontrol etmeden imza uzunluğunu hesaplar.

Show the technical text from the sources

`_nx_secure_x509_parse_signature_data` computes the certificate signature's length as `tlv_length - 1` without first checking that `tlv_length` is non-zero. A certificate whose signature is an empty ASN.1 BIT STRING therefore parses successfully and leaves the certificate holding a signature length of `0xFFFFFFFF` and a signature pointer one byte past the end of the buffer. Certificates are parsed from the peer during the TLS handshake, so the input is remote and unauthenticated.
