affected by a vulnerability as referenced in the USN-7471-1 advisory.

    It was discovered that poppler did not properly verify adbe.pkcs7.sha1 signatures in PDF documents. An
    attacker could possibly use this issue to create documents with forged signatures that are treated as
    legitimately signed.

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
