"The remote EulerOS host is missing multiple security updates.");

"According to the versions of the perl-DBI packages installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

    DBI versions before 1.650 for Perl have a heap overflow when preparsing SQL statements with an extreme
    number of placeholders._x000D_
    _x000D_
    The fix for CVE-2026-10879 did not allocate enough memory to handle approximately 1.2-million
    placeholders._x000D_
    _x000D_
    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._x000D_
    _x000D_
    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._x000D_
    _x000D_
    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._x000D_
    _x000D_
    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._x000D_
    _x000D_
    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)

    DBI versions before 1.648 for Perl saved errors in a limited-sized buffer._x000D_
    _x000D_
    Error messages that were returned when RaiseError, PrintError or HandleError were set were written to a
    200-byte buffer without a length limit._x000D_
    _x000D_
    Attackers that can influence the error text in an application can trigger a buffer
    overflow.(CVE-2026-9698)

    DBI::ProfileData versions before 1.651 for Perl do not limit the path index._x000D_
    _x000D_
    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 1.651 for Perl do not enforce statement handle consistency with the row._x000D_
    _x000D_
    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._x000D_
    _x000D_
    This could be triggered by a caller supplying inconsistent metadata and rows to the prepare
    method.(CVE-2026-60082)
