Amazon Linux 2023 Security Advisory: ALAS2023-2026-1850
Advisory Released Date: 2026-06-22
Advisory Updated Date: 2026-06-22
Severity:
Important
Issue Overview:
DBI versions before 1.648 for Perl have a heap overflow when preparsing SQL statements with more than 9 binders.
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 versions before 1.648 for Perl saved errors in a limited-sized buffer. Error messages that were returned when RaiseError, PrintError or HandleError were set were written to a 200-byte buffer without a length limit. Attackers that can influence the error text in an application can trigger a buffer overflow. (CVE-2026-9698)
Affected Packages:
perl-DBI
Issue Correction:
