There is a NULL pointer dereference in the AnnotPath::getCoordsLength function in Annot.h in an Ubuntu package for Poppler 0.24.5. A crafted input will lead to a remote denial of service attack. Later Ubuntu packages such as for Poppler 0.41.0 are not affected.

Security readout for executives and security teams

Plain-English summary

CVE-2018-10768 is a crash bug in Poppler, a PDF-processing component. In the affected Ubuntu Poppler 0.24.5 package, crafted input can trigger a NULL pointer dereference and cause remote denial of service. Later Ubuntu packages such as Poppler 0.41.0 are stated as not affected.

Executive priority

Prioritize remediation for systems that automatically parse documents from outside the organization. The likely impact is service disruption, not confirmed data compromise. Patch through normal vendor channels, with urgency increased for internet-facing upload or document-preview services.

Technical view

The issue is a NULL pointer dereference in AnnotPath::getCoordsLength in Annot.h. The source bundle describes denial of service from crafted input, with vendor advisories from Ubuntu, Debian LTS, and Red Hat. No CVSS, CWE, CPE, exploit details, or patch commit is provided in the bundle.

Likely exposure

Exposure is most likely where older Poppler packages process untrusted PDF or document input, especially upload, email, indexing, or preview workflows. The bundle specifically names an Ubuntu Poppler 0.24.5 package and states later Ubuntu 0.41.0 packages are not affected.

Exploitation context

The bundle supports remote denial of service through crafted input. It does not show CISA KEV listing, active exploitation, weaponization, or code-execution impact. Treat internet-facing or automated document parsing as higher operational risk because crashes can disrupt service availability.

Researcher notes

Evidence is limited but consistent: a NULL dereference in Poppler’s annotation path handling causes denial of service. The bundle lacks affected CPEs, CVSS scoring, CWE mapping, and exploit status. Avoid broad product claims beyond the named Poppler package and cited vendor advisories.

Mitigation direction

  • Apply relevant Ubuntu, Debian LTS, or Red Hat Poppler security updates.
  • Retire or isolate the affected Ubuntu Poppler 0.24.5 package.
  • Use vendor advisories to identify fixed package versions for each distribution.
  • Limit untrusted document processing exposure where updates cannot be applied.
  • Monitor document-processing services for crashes after handling external files.

Validation and detection

  • Inventory installed Poppler package names and versions across Linux systems.
  • Check for Ubuntu Poppler 0.24.5 or advisory-affected distribution packages.
  • Confirm applicable USN, DLA, or RHSA updates are installed.
  • Identify services that parse PDFs from uploads, email, or external feeds.
  • Review crash logs for Poppler NULL dereference symptoms.
