| Detailed Description |
The version of OpenSSL installed on the remote host is prior to 3.0.8. It is, therefore, affected by a denial of service (DoS) vulnerability.
If an X.509 certificate contains a malformed policy constraint and policy processing is enabled, then a write lock will be taken twice recursively. On some operating systems (most widely: Windows) this results in a denial of service when the affected process hangs. Policy processing being enabled on a publicly facing server is not considered to be a common setup. Policy processing is enabled by passing the -policy argument to the command line utilities or by calling either X509_VERIFY_PARAM_add0_policy() or X509_VERIFY_PARAM_set1_policies() functions.
Note that due to the low severity of the issue, no fix was available at the time the advisory was published. A fix will be present in 3.0.8.
