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)
