vulnerability :

  - A buffer overflow was found in perl-DBI < 1.643 in

    longer than 300 characters could cause an out-of-bounds
    write, affecting the availability of the service or
    integrity of data.(CVE-2020-14393)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
