Package : libdbi-perl Version : 1.643-3+deb11u2 1.643-4+deb12u2 CVE ID : CVE-2026-14380 CVE-2026-14739 CVE-2026-14740 CVE-2026-15043 CVE-2026-15392 CVE-2026-60081 CVE-2026-60082 CVE-2026-73193 CVE-2026-73194 Debian Bug : 1141667 1142072 1144470 1144471

Multiple vulnerabilities were discovered in libdbi-perl, the Perl Database Interface (DBI), which may lead to arbitrary code execution, denial of service, file-backed filter bypass or path traversal.

CVE-2026-14380

It was found that missing input validation when interpolating the package name in a string `eval` may lead to arbitrary Perl code execution from an attacker able controlling the Profile attribute, for instance via the `DBI_PROFILE` environment variable or a DSN driver-attribute clause `dbi:Driver(Profile=>SPEC):db`.

CVE-2026-14739

It was found that preparsing SQL statements with an excessively high (over one million) number of placeholders could lead to heap overflow.

This update sets a hard limit of 99999 placeholders.

CVE-2026-14740

It was found that preparsing an SQL statement starting with a comment line could lead to an out-of-bounds read by one byte.

CVE-2026-15043

It was found that DBI::SQL::Nano, DBI's built-in mini-SQL engine, evaluated `WHERE` predicates by incorrectly inverting `<=` and `>=` SQL operators on text, which may lead to file-backed filter bypass.

CVE-2026-15392

It was found that DBD::File did not check whether the table file is a symbolic link, which may lead to path traversal if the target points outside the `f_dir` and `f_dir_search` directories.

This issue stems from an incomplete fix for CVE-2014-10401 and CVE-2014-10402.

CVE-2026-60081

It was found that DBI::ProfileData did not limit the path index when parsing a profile-dump file, which may lead to denial of service.

This updates adds a configurable maximum path depth `$DBI::Profile::MAX_PATH_DEPTH`, with a default value of 256.

CVE-2026-60082

It was found that missing statement handle consistency checks could lead to an out-of-bounds read when a statement handle had no fields and the source row was non-empty.

CVE-2026-73193

A heap out-of-bounds write issue was found on 32-bit platforms due to integer overflow in the output buffer size computed by the `preparse()` function.

This updates limits the size of SQL statements to 292 MiB.

CVE-2026-73194

A heap out-of-bounds write issue was found due to unvalidated numeric placeholder in the `preparse()` function.

This issue stems from an incomplete fix for CVE-2026-14739.

For Debian 11 bullseye, these problems have been fixed in version 1.643-3+deb11u2.

For Debian 12 bookworm, these problems have been fixed in version 1.643-4+deb12u2.

We recommend that you upgrade your libdbi-perl packages.
