"The remote EulerOS Virtualization host is missing multiple security updates.");
  script_set_attribute(attribute:"description", value:
"According to the versions of the perl-DBI package installed, the EulerOS Virtualization installation on the remote host
is affected by the following vulnerabilities :

    DBI::ProfileData versions before 1.651 for Perl do not limit the path index.The path index column of
    profile dump files is used to allocate an array of data for the parser. An unbounded value allows an
    attacker to specify a large index and consume available memory.(CVE-2026-60081)

    DBI versions before 1.648 for Perl saved errors in a limited-sized buffer.Error messages that were
    returned when RaiseError, PrintError or HandleError were set were written to a 200-byte buffer without a
    length limit.Attackers that can influence the error text in an application can trigger a buffer
    overflow.(CVE-2026-9698)

    DBI versions before 1.651 for Perl do not enforce statement handle consistency with the row.When the
    statement handle had no fields but the source row was non-empty, the internal row-buffer helper would read
    from a negative array index.This could be triggered by a caller supplying inconsistent metadata and rows
    to the prepare method.(CVE-2026-60082)

    DBI versions before 1.650 for Perl have a heap overflow when preparsing SQL statements with an extreme
    number of placeholders.The fix for CVE-2026-10879 did not allocate enough memory to handle approximately
    1.2-million placeholders.DBI version 1.650 sets a hard limit of 99,999 placeholders.(CVE-2026-14739)

    DBI versions before 1.648 for Perl have a heap overflow when preparsing SQL statements with more than 9
    binders.The preparse method expands SQL placeholder characters to numbered binders of the form :pN, but
    only allocates three characters per binder in the buffer.  Placeholders 10-99 require four characters,
    100-999 require five characters, et cetera.(CVE-2026-10879)

    DBI::SQL::Nano versions from 1.42 before 1.651 for Perl have inverted = and = SQL operators on
    text.DBI::SQL::Nano, DBI's built-in mini-SQL engine, evaluated WHERE predicates incorrectly in some cases.
    In the non-numeric string branch of the is_matched method, = was evaluated using Perl's ge operator,
    and = was evaluated using Perl's le operator.SQL::Nano is the fallback query engine for DBI's file-
    backed drivers (DBD::File, DBD::DBM, CSV-style drivers) whenever SQL::Statement is not installed, and is
    forced whenever DBI_SQL_NANO=1. Queries over such tables use these predicates directly.The impact depends
    on the context. Where an application relies on a WHERE clause to filter file-backed data for policy or
    authorization, an inverted =/= comparison silently returns the wrong rows.(CVE-2026-15043)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization perl-DBI security
advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
