Summary
Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2026-9698: 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-2026-10879: 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.
