AI-suggested
A patch is available in MariaDB Connector/J versions 3.3.7, 3.4.5, and 3.5.11 that validates gtrid_length and bqual_length values before allocation and copying during XA recovery. Users should upgrade to these fixed versions to remediate the vulnerability. No additional mitigation is required if patched.
Description
MariaDB Connector/J versions 3.0.0 through before 3.3.7, 3.4.0 through before 3.4.5, and 3.5.0 through before 3.5.11 contain a vulnerability in the XAResource.recover() method. The method trusts server-supplied gtrid_length and bqual_length values without validating them against XA specification bounds, leading to potential large memory allocations or exceptions during XA recovery. This can cause availability issues such as crashes or denial of service. Exploitation requires control over the server side of the connection. Fixed versions are 3.3.7, 3.4.5, and 3.5.11.
