CWE-835  (opens in a new tab)

How to fix?

Overview

Affected versions of this package are vulnerable to Infinite loop via the BN_mod_sqrt() function when parsing certificates. It is possible to trigger this vulnerability by crafting a certificate that has invalid explicit curve parameters. Since certificate parsing happens before verification of the certificate signature, any process that parses an externally supplied certificate may be subject to a denial of service attack.
