The remote Oracle Linux 5 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2013-1458 advisory.

    - fix CVE-2013-4351 gpg treats no-usage-permitted keys as all-usages-permitted
    - fix CVE-2012-6085 GnuPG: read_block() corrupt key input validation
    - fix CVE-2013-4242 GnuPG susceptible to Yarom/Falkner side-channel attack
    - fix CVE-2013-4402 GnuPG: infinite recursion in the compressed packet parser

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2013:1459 advisory.

    The GNU Privacy Guard (GnuPG or GPG) is a tool for encrypting data and     creating digital signatures, compliant with the proposed OpenPGP Internet     standard and the S/MIME standard.

    A denial of service flaw was found in the way GnuPG parsed certain     compressed OpenPGP packets. An attacker could use this flaw to send     specially crafted input data to GnuPG, making GnuPG enter an infinite loop     when parsing data. (CVE-2013-4402)

    It was found that importing a corrupted public key into a GnuPG keyring     database corrupted that keyring. An attacker could use this flaw to trick a     local user into importing a specially crafted public key into their keyring     database, causing the keyring to be corrupted and preventing its further     use. (CVE-2012-6085)

    It was found that GnuPG did not properly interpret the key flags in a PGP     key packet. GPG could accept a key for uses not indicated by its holder.
    (CVE-2013-4351)

    Red Hat would like to thank Werner Koch for reporting the CVE-2013-4402     issue. Upstream acknowledges Taylor R Campbell as the original reporter.

    All gnupg2 users are advised to upgrade to this updated package, which     contains backported patches to correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An updated gnupg2 package that fixes three security issues is now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
