A vulnerability in the OpenSSL cryptographic library is related to the validation of X.509 certificate chains that
include policy restrictions. Exploitation of the vulnerability could allow an attacker acting

of computing resources, resulting in a denial of service (DoS) attack on vulnerable systems.
