poppler vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 25.04
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS

Summary:

poppler could be made to crash or run programs if it opened a specially
crafted file.

Software Description:
- poppler: PDF rendering library

Details:

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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 25.04
  libpoppler147                   25.03.0-3ubuntu1.1
  poppler-utils                   25.03.0-3ubuntu1.1

Ubuntu 24.04 LTS
  libpoppler134                   24.02.0-1ubuntu9.5
  poppler-utils                   24.02.0-1ubuntu9.5
