Several security issues were fixed in poppler.

Summary

Several security issues were fixed in poppler.

Software Description:

- poppler: PDF rendering library

Details:

Jieyong Ma discovered that poppler incorrectly handled certain malformed

PDF files. A remote attacker could possibly use this issue to cause poppler

to crash, resulting in a denial of service. This issue only affected Ubuntu

16.04 LTS and Ubuntu 18.04 LTS. (CVE-2022-27337)

Kevin Backhouse discovered that poppler incorrectly handled documents with

a large number of annotations. If a user or automated system were tricked

into opening a specially crafted document, a remote attacker could use

this issue to cause poppler to consume resources, leading to a denial of

service, or possibly execute arbitrary code. (CVE-2025-52886)
