CVE-2015-2582

What it actually does

Unspecified flaw in GIS handling allows an authenticated remote user to trigger a denial-of-service condition that reduces MySQL Server availability.

Why it matters to the business

Database instances become unavailable, interrupting applications and services that depend on MySQL or MariaDB and potentially causing operational downtime.

How an attack unfolds

An attacker who already possesses a valid database account crafts and submits GIS-related queries or data that exploit the flaw, causing the server process to crash or hang.

How to fix it

Upgrade Oracle MySQL to versions later than 5.5.43 and 5.6.24, or apply the corresponding security patches provided by MariaDB, Canonical, Red Hat, Debian, or Oracle Solaris. Restart affected services after upgrade and verify the new version string.

How to confirm the fix worked

Compare the running server version against the fixed releases listed in vendor advisories; attempt to reproduce the GIS vector in a test environment and confirm the server no longer crashes.

Typical attack path

1. Obtain valid database credentials on the target MySQL/MariaDB instance
2. Connect over the network and issue crafted GIS queries or insert malicious spatial data
3. Trigger the vulnerability to induce server crash or resource exhaustion
4. Repeat or combine with other actions to prolong denial of service

How to detect it

Review MySQL error logs and crash reports for entries mentioning GIS functions or spatial operations around the time of unexpected server restarts; correlate with authenticated user activity in the general query log.

What your security team should do

• Apply vendor patches to all MySQL and MariaDB deployments as soon as possible
• Restrict database accounts to the minimum required privileges and network sources
• Monitor database error and crash logs for GIS-related failures
• Segment database servers and enforce network access controls to limit authenticated attack surface
