Subject: [PATCH] Replacing `?` with `:p#` in `preparse ()` with more than 9
`?` causes buffer overflow
`:p1` is length 3, `?` just 1, but `:p1003` is length 6!
CVE: CVE-2026-10879
Upstream-Status: Backport [https://github.com/perl5-dbi/dbi/commit/af79036c07aa9a457971c0f4136e37c85dc20978]
Backport Changes:
- Applied the DBI.xs security fix without functional changes.
- Omitted ChangeLog and lib/DBI/Changes.pm because they contain only
DBI 1.648 release-note updates.
- Omitted dbixs_rev.h because it is generated from upstream Git history
and its hunk only updates the generated timestamp and revision. The
fix does not change the DBIXS or DBISTATE interface.
- Omitted doc/DBI.3 and doc/DBI.man because they are generated manual
pages that only contain regenerated dates and are absent from the
DBI 1.647 CPAN source.
(cherry picked from commit af79036c07aa9a457971c0f4136e37c85dc20978)
