CVE-2026-10879: CWE-787 (Out-of-bounds Write) in HMBRAND DBI
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.
AI Analysis
Technical Summary
The vulnerability in HMBRAND DBI affects versions prior to 1.648 and is caused by improper buffer allocation in the preparse method when processing SQL placeholders. Specifically, the method expands placeholders into numbered binders like :pN but only allocates three characters per binder. This allocation is insufficient for binders numbered 10 and above, which require four or more characters, resulting in a heap overflow (CWE-787). No patch or official remediation information is currently available.
Potential Impact
The heap overflow could potentially lead to memory corruption, which might be exploitable to cause crashes or arbitrary code execution. However, no known exploits are reported in the wild at this time. The lack of a CVSS score and detailed impact data limits precise severity assessment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should avoid using SQL statements with more than 9 binders in affected DBI versions or consider upgrading to version 1.648 or later once released.
