CVE-2019-1010127: VCFTools vcftools prior to version 0.1.15 is affected by: Use-after-free.

VCFTools vcftools prior to version 0.1.15 is affected by: Use-after-free. The impact is: Denial of Service or possibly other impact (eg. code execution or information disclosure). The component is: The header::add_FILTER_descriptor method in header.cpp. The attack vector is: The victim must open a specially crafted VCF file.

Security readout for executives and security teams

Plain-English summary

VCFTools versions before 0.1.15 can mishandle a specially crafted VCF file and may crash or have other memory-safety impact. The known trigger requires the victim or pipeline to open a malicious VCF. There is no source-provided evidence of active exploitation.

Executive priority

Prioritize remediation where VCFTools processes externally supplied VCF files or runs in shared analysis infrastructure. For isolated, trusted-only use, urgency is lower, but the missing severity score keeps residual risk uncertain.

Technical view

CVE-2019-1010127 is a use-after-free in VCFTools before 0.1.15, specifically header::add_FILTER_descriptor in header.cpp. Sources state impact as denial of service or possibly code execution or information disclosure, but do not provide CVSS, CWE, confirmed exploitation, or detailed remediation beyond affected version bounds.

Likely exposure

Exposure is most likely in genomics research, bioinformatics pipelines, or workstations that process VCF files using VCFTools before 0.1.15, especially where files come from collaborators, uploads, public datasets, or automated intake workflows.

Exploitation context

The attack vector is file-based: a user or automated job must open a specially crafted VCF file. The source bundle does not show public exploit status, KEV listing, or in-the-wild exploitation evidence.

Researcher notes

The available record names the vulnerable method and broad impact category but lacks CVSS, CWE, exploit confirmation, patch commit detail, and reproducibility context. Treat code execution and information disclosure as possible but unconfirmed from the supplied sources.

Mitigation direction

  • Upgrade VCFTools installations older than 0.1.15 to version 0.1.15 or later.
  • Restrict automated processing of external VCF files until affected systems are updated.
  • Handle collaborator, upload, and public dataset VCFs as untrusted input.
  • Check VCFTools project guidance for any additional vendor-recommended remediation.

Validation and detection

  • Inventory VCFTools versions across workstations, servers, containers, and workflow images.
  • Identify pipelines that parse VCF files from external or semi-trusted sources.
  • Confirm production images and job runners no longer use versions before 0.1.15.
  • Review recent VCFTools crashes during VCF parsing for possible suspicious input handling.
