Summary
Important: perl-DBI security update
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):
- perl-DBI: perl-DBI: Heap overflow in SQL preparsing can lead to denial of service or arbitrary code execution. (CVE-2026-10879)
- DBI: DBI: Buffer overflow in error handling can lead to arbitrary code execution (CVE-2026-9698)
- DBI: DBI: Arbitrary code execution via caller-influenced Profile attribute (CVE-2026-14380)
- DBI: DBI: Heap overflow when preparsing SQL statements with excessive placeholders (CVE-2026-14739)
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.

Title
DBI versions before 1.648 for Perl have a heap overflow when preparsing SQL statements with more than 9 binders
Summary
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.

Title
DBI versions before 1.650 for Perl are vulnerable to code injection via caller-influenced Profile
Summary
DBI versions before 1.650 for Perl are vulnerable to code injection via caller-influenced Profile.
When a string is assigned to a DBI handle's Profile attribute, DBI splits it into path, package and arguments, and interpolates the package part in a string eval with no validation of the package name.
Any caller-influenced value that reaches the Profile attribute is therefore arbitrary Perl code execution, including calls to run system commands.
The Profile attribute can be set from three different sources that can carry untrusted data: the DBI_PROFILE environment variable, a direct attribute assignment, and a DSN driver-attribute clause dbi:Driver(Profile=>SPEC):db.
An attacker controlling any of those inputs runs arbitrary Perl in the host process. The strongest remote position is a network-exposed DBI::Gofer / DBI::ProxyServer whose per-request DSN reaches the Profile attribute, letting a client execute code on the broker host.

Title
DBI versions before 1.650 for Perl have a heap overflow when preparsing SQL statements with an extreme number of placeholders
Summary
DBI versions before 1.650 for Perl have a heap overflow when preparsing SQL statements with an extreme number of placeholders.
The fix for CVE-2026-10879 did not allocate enough memory to handle approximately 1.2-million placeholders.
DBI version 1.650 sets a hard limit of 99,999 placeholders.

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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
