Security readout for executives and security teams
Plain-English summary
CVE-2018-11739 affects The Sleuth Kit releases 4.0.2 through 4.6.1. A crafted or otherwise malicious image handled by libtskimg.a could cause the tool to read memory outside the intended bounds, potentially exposing information or crashing the process.
Executive priority
Treat as a targeted operational risk for forensic or image-processing systems, not a broad enterprise emergency based on current evidence.
Technical view
The reported flaw is an out-of-bounds read in raw_read within tsk/img/raw.c in libtskimg.a. The source states it may disclose information or read unmapped memory, causing denial of service. No CVSS, CWE, fixed version, or active exploitation evidence is provided in the bundle.
Likely exposure
Exposure is most likely where The Sleuth Kit 4.0.2 through 4.6.1 or applications linked against libtskimg.a process untrusted disk image data.
Exploitation context
The source bundle does not show KEV listing or active exploitation. Risk depends on whether vulnerable TSK components process attacker-controlled or untrusted image files.
Researcher notes
The available record names the vulnerable function and affected release range but lacks CVSS, CWE, patch details, and exploitation evidence. Validate exposure through dependency inventory and input-trust boundaries.
Mitigation direction
- Inventory The Sleuth Kit versions and libtskimg.a dependencies.
- Check The Sleuth Kit vendor issue for fixed release or maintainer guidance.
- Avoid processing untrusted images on vulnerable versions where possible.
- Run image-processing workflows in isolated, least-privileged environments.
- Monitor for unexpected crashes in TSK-based processing jobs.
Validation and detection
- Confirm whether installed TSK versions are 4.0.2 through 4.6.1.
- Identify products or scripts statically linking or bundling libtskimg.a.
- Review data flows for untrusted disk image ingestion.
- Check crash reports for failures involving raw_read or tsk/img/raw.c.
- Document compensating controls for any vulnerable deployments.
