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 the `X509_VERIFY_PARAM_set1_policies()' function. Update (31 March 2023): The description of the policy processing enablement was corrected based on CVE-2023-0466.

AltaVault OST Plug-in versions prior to 1.2.2 may allow attackers to obtain sensitive information via unspecified vectors. All users are urged to move to a fixed version and change passwords used by Veritas NetBackup to access the OST shares on the NetApp AltaVault as a precaution.
