This could cause the 64 octet limit on the local part of an email address to be not enforced, or cause an out of bound read and potentially a crash.</p> <p>The bug is reachable via S-MIME validation with a crafted From: address supplied in an email message that can potentially cause a crash.</p> <p>No FIPS modules are affected by this issue as the affected code is outside the OpenSSL FIPS module boundary.</p> <p><strong>Affected:</strong> OpenSSL</p> <p>Issue summary: When the X509_VERIFY_PARAM_set1_email is called by an application to validate a crafted e-mail address, such as during S/MIME message validation, an out of bounds read can happen.</p> <p>Impact summary: This out of bounds read will not directly exfiltrate the data read to the attacker so the most likely result is a crash and a Denial of Service.</p> <p>An internal helper function called from X509_VERIFY_PARAM_[set|add]_email() used a wrong length when validating the local part of an email address.
