DBI-1.645
⭐ Starred 84 / DBI::Util::CacheMemory
Security Advisories (1)
CVE-2026-10879 (2026-06-05)

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.

NAME

DBI::Util::CacheMemory - a very fast but very minimal subset of Cache::Memory

DESCRIPTION

Like Cache::Memory (part of the Cache distribution) but doesn't support any fancy features.

This module aims to be a very fast compatible strict sub-set for simple cases, such as basic client-side caching for DBD::Gofer.

Like Cache::Memory, and other caches in the Cache and Cache::Cache distributions, the data will remain in the cache until cleared, it expires, or the process dies. The cache object simply going out of scope will not destroy the data.

METHODS WITH CHANGES

new

All options except namespace are ignored.

set

Doesn't support expiry.

purge

Same as clear() - deletes everything in the namespace.

METHODS WITHOUT CHANGES

clear
count
exists
remove

UNSUPPORTED METHODS

If it's not listed above, it's not supported.
