"The remote host is affected by the vulnerability described in GLSA-200506-06
(libextractor: Multiple overflow vulnerabilities)

    Xpdf is vulnerable to multiple overflows, as described in GLSA
    200501-28. Also, integer overflows were discovered in Real and PNG
    extractors.
  
Impact :

    An attacker could design malicious PDF, PNG or Real files which,
    when processed by an application making use of libextractor, would
    result in the execution of arbitrary code with the rights of the user
    running the application.
  
Workaround :

    There is no known workaround at this time."
