FKIE_CVE-2026-14740

Vulnerability from fkie_nvd - Published: 2026-07-07 23:16 - Updated: 2026-07-10 14:40
Severity
9.1 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H
Summary
DBI versions before 1.650 for Perl read one byte out-of-bounds in preparse when deleting an initial SQL comment. The preparse method normalises SQL and removes comments. When the SQL starts with a comment line, the deletion of that line during normalisation led to an out-of-bounds read by one byte. The result is a fault on memory-hardened builds and nondeterministic newline retention on normal builds.
