that are affected by a vulnerability as referenced in the USN-7545-1 advisory.

    Qualys discovered that Apport incorrectly handled metadata when processing application crashes. An
    attacker could possibly use this issue to leak sensitive information.

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
