    Hosein Askari discovered that poppler incorrectly handled certain PDF files. An attacker could possible
    use this issue to cause a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
