EulerOS 2.0 SP15 : perl-DBI (EulerOS-SA-2026-4001)

critical Nessus Plugin ID 363990

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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)

Tenable has extracted the preceding description block directly from the EulerOS 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.

Solution

Update the affected perl-DBI packages.
