Summary

mariadb-connector-c security update

Details

This package is used for connecting C/C++ programs to MariaDB and MySQL database.

Security Fix(es):

MariaDB server is a community developed fork of MySQL server. In versions 3.3.18 and 3.4.8, an application that was taking non-validated user input, escaping it with mysql_real_escape_string() and sending it to the database using text protocol and big5 character set was vulnerable to SQL injections, even though mysql_real_escape_string() was supposed to prevent them. This issue has been patched in versions 3.3.19 and 3.4.9.(CVE-2026-44172)

Severity

9.1 (Critical)
