Disclaimer: Community trackers are created by Red Hat Product Security team on
a best effort basis. Package maintainers are required to ascertain if the flaw
indeed affects their package, before starting the update process.
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.
