The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2013:1135 advisory.

    Network Security Services (NSS) is a set of libraries designed to support     the cross-platform development of security-enabled client and server     applications. Netscape Portable Runtime (NSPR) provides platform     independence for non-GUI operating system facilities.

    It was discovered that NSS leaked timing information when decrypting     TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites     were used. A remote attacker could possibly use this flaw to retrieve plain     text from the encrypted packets by using a TLS/SSL or DTLS server as a     padding oracle. (CVE-2013-1620)

    An out-of-bounds memory read flaw was found in the way NSS decoded certain     certificates. If an application using NSS decoded a malformed certificate,     it could cause the application to crash. (CVE-2013-0791)

    Red Hat would like to thank the Mozilla project for reporting     CVE-2013-0791. Upstream acknowledges Ambroz Bizjak as the original reporter     of CVE-2013-0791.

    This update also fixes the following bugs:

    * A defect in the FreeBL library implementation of the Diffie-Hellman (DH)     protocol previously caused Openswan to drop connections. (BZ#958023)

     * A memory leak in the nssutil_ReadSecmodDB() function has been fixed.
    (BZ#986969)

    In addition, the nss package has been upgraded to upstream version 3.14.3,     and the nspr package has been upgraded to upstream version 4.9.5. These     updates provide a number of bug fixes and enhancements over the previous     versions. (BZ#949845, BZ#924741)

    Note that while upstream NSS version 3.14 prevents the use of certificates     that have an MD5 signature, this erratum includes a patch that allows such     certificates by default. To prevent the use of certificates that have an     MD5 signature, set the NSS_HASH_ALG_SUPPORT environment variable     to -MD5.

    Users of NSS and NSPR are advised to upgrade to these updated packages,     which fix these issues and add these enhancements. After installing this     update, applications using NSS or NSPR must be restarted for this update to     take effect.

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.
