Frequently Asked Questions
What does an attacker need to exploit these issues?
The supplied CVSS vector indicates that no privileges are required, exploitation can be initiated remotely, and user interaction is required. Public exploits are reported for the JBIG2Stream issues, so processing attacker-controlled content should be treated as a realistic exposure path.
Which systems should be prioritized for remediation?
Prioritize openEuler systems using Poppler, especially where the affected upstream Poppler 26.07.0 code is present. The reported impacts include low confidentiality, integrity, and availability effects.
What remediation is identified in the advisory?
Upgrade to Poppler 26.08.0 for CVE-2026-93312. The advisory identifies patch 5e49250f13b0390edeb3f90eb4c02c9941f97067 for that issue and patch eb87cf711563894649bd0c365baa479401dc6d51 for CVE-2026-93313.
How can I check whether my build includes the identified fixes?
Check the installed Poppler version and, for source-based or backported builds, verify whether the identified patch commits are present. The explicitly affected upstream version in the advisory is 26.07.0.
