Threats affecting pkg:rpm/redhat/perl-DBI

The perl-DBI package provides the standard database interface module for the Perl programming language. It implements a database-independent interface, meaning it defines a consistent set of methods, variables, and conventions for database operations. Security Fix(es): * perl-DBI: perl-DBI: Denial of Service via invalid memory read during numeric type casting (CVE-2026-88815) 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.

DBI versions before 1.652 for Perl allow a heap out-of-bounds write via an unvalidated numeric placeholder that sets the binder counter in preparse. preparse reserves seven output bytes per input byte, the width of the longest ':p99999' expansion. The ':N' branch parses the number with `atoi(src)` and assigns it to the binder counter with no range check, so a statement containing ':2147483648' leaves the counter negative (-2147483648 with glibc, where atoi wraps). Each following '?' then expands through `sprintf(start, ":p%d", idx++)` to ':p-2147483648', 14 bytes with the terminating NUL where the buffer budgets 7. The placeholder limit added in 1.650 tests the counter against 99,999, which a negative counter passes. Any caller that preparses an untrusted statement into ':pN' style placeholders gets a heap out-of-bounds write that grows with the number of '?' marks following the poisoned placeholder. The '?' and '%s' return styles compare the parsed number against the expected sequence and error out, and are unaffected.

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: Incomplete fix for CVE-2026-14380 DBI: Arbitrary code execution via caller-influenced Profile attribute (CVE-2026-19546) 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.

Two security vulnerabilities were identified in the perl-DBI package. CVE-2026-14380 allows arbitrary Perl code execution due to unvalidated string eval interpolation of the Profile package name. CVE-2026-14740 causes a one-byte out-of-bounds read when deleting an initial SQL comment line, potentially leading to a process crash. These issues affect certain versions of perl-DBI and have been addressed by security updates.
