CVE-2026-9698
DBI versions before 1.648 for Perl saved errors in a limited-sized buffer
Overview
Description

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.

    Added Translation Title: DBI de HMBRAND, Description: Las versiones de DBI anteriores a la 1.648 para Perl guardaban errores en un búfer de tamaño limitado. Los mensajes de error que se devolvían cuando RaiseError, PrintError o HandleError estaban configurados se escribían en un búfer de 200 bytes sin un límite de longitud. Los atacantes que pueden influir en el texto de error en una aplicación pueden desencadenar un desbordamiento de búfer.
