AI-Generated

MariaDB servers from versions 10.6.1 to 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2 are vulnerable due to insufficient validation of FRM metadata, allowing attackers to exploit crafted binary FRM files. This could lead to out-of-bounds reads or writes, server crashes, or potential code execution. Organizations using affected MariaDB versions should prioritize upgrading to the patched releases to mitigate these risks.

Original NVD Description

MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, MariaDB insufficiently validated counts, offsets, lengths, and field boundaries in FRM metadata while opening binary FRM files. An attacker able to place a crafted FRM file in the data directory could trigger out-of-bounds reads or writes, crash the server, or potentially execute code. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.
