Affected: HMBRAND DBI, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat Insights proxy 1.5, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7

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.

Affected: Ubuntu:Pro:14.04:LTS: libdbi-perl, Ubuntu:Pro:16.04:LTS: libdbi-perl, Ubuntu:Pro:18.04:LTS: libdbi-perl, Ubuntu:Pro:20.04:LTS: libdbi-perl, Ubuntu:22.04:LTS: libdbi-perl, Ubuntu:24.04:LTS: libdbi-perl, Ubuntu:25.10: libdbi-perl, Ubuntu:26.04:LTS: libdbi-perl

It was discovered that the Perl DBI module incorrectly handled certain error messages. An attacker could use this issue to cause applications using the Perl DBI module to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2026-9698)

It was discovered that the Perl DBI module incorrectly handled memory when preparsing SQL statements that included more than nine binders. An attacker could use this issue to cause applications using the Perl DBI module to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2026-10879)
