Description

According to the version of the pam package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

 - It was discovered that the _unix_run_helper_binary() function of PAM's unix_pam module could write to a blocking pipe, possibly causing the function to become unresponsive.
