"According to the versions of the perl-DBI package installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - An issue was discovered in the DBI module before 1.643
    for Perl. The hv_fetch() documentation requires
    checking for NULL and the code does that. But, shortly
    thereafter, it calls SvOK(profile), causing a NULL
    pointer dereference.(CVE-2019-20919)

  - A buffer overflow was found in perl-DBI < 1.643 in
    DBI.xs. A local attacker who is able to supply a string
    longer than 300 characters could cause an out-of-bounds
    write, affecting the availability of the service or
    integrity of data.(CVE-2020-14393)

  - An untrusted pointer dereference flaw was found in
    Perl-DBI < 1.643. A local attacker who is able to
    manipulate calls to dbd_db_login6_sv() could cause
    memory corruption, affecting the service's
    availability.(CVE-2020-14392)

  - An issue was discovered in the DBI module through 1.643
    for Perl. DBD::File drivers can open files from folders
    other than those specifically passed via the f_dir
    attribute in the data source name (DSN). NOTE: this
    issue exists because of an incomplete fix for
    CVE-2014-10401.(CVE-2014-10402)

Note that Tenable Network Security has extracted the preceding
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.");
