Summary

Red Hat Security Advisory: perl-DBI security update

Severity

Important

Notes

Topic: An update for perl-DBI is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details: DBI is a database access Application Programming Interface (API) for the Perl Language. The DBI API Specification defines a set of functions, variables and conventions that provide a consistent database interface independent of the actual database being used. Security Fix(es): * DBI: DBI: Buffer overflow in error handling can lead to arbitrary code execution (CVE-2026-9698) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE-2026-9698

A flaw was found in DBI, a Perl database interface. This vulnerability allows an attacker to trigger a buffer overflow by manipulating error messages within an application. When specific error handling options are active, an attacker can provide oversized error text, which may lead to arbitrary code execution or a denial of service (DoS).

8.2 (High)


                        
                          CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H

CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

CVE-2026-9698 (GCVE-0-2026-9698)

Vulnerability from cvelistv5 – Published: 2026-06-09 07:22 – Updated: 2026-07-13 12:05

Title

DBI versions before 1.648 for Perl saved errors in a limited-sized buffer

Summary

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.

Severity

7.5 (High)
