CVE-2016-6153

What it actually does

SQLite uses the current working directory for temporary files due to an improper search algorithm in os_unix.c, allowing local interference with file creation that can expose data, trigger crashes, or enable other local impacts.

Why it matters to the business

Systems relying on older SQLite versions face limited local risks of data exposure or application disruption, with low likelihood of widespread exploitation given the age and local-only nature of the issue.

How an attack unfolds

A local attacker identifies an SQLite process running from a writable directory, places crafted files there to influence temporary file operations, and triggers database activity to cause unintended file access or application instability.

How to fix it

Upgrade SQLite to version 3.13.0 or later across all affected products including sqlite, fedora, and opensuse leap to enforce secure temporary directory selection.

How to confirm the fix worked

Confirm installed SQLite version is 3.13.0 or newer; verify temporary files are created only in designated secure locations rather than the current working directory.

Typical attack path

1. Obtain local access on the target system
2. Locate SQLite processes using the current working directory
3. Prepare directory contents to affect temporary file handling
4. Induce SQLite operations that exercise the flawed temp directory logic

How to detect it

Review system and application logs for SQLite temporary file creation in unexpected directories or associated crashes; examine process execution context for working directory usage patterns.

What your security team should do

• Apply the 3.13.0 update immediately on all SQLite deployments
• Review applications that bundle or depend on older SQLite for local file handling assumptions
• Restrict local user write access to directories from which database processes execute
