"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2012-458:01 advisory.

    GnuTLS is a project that aims to develop a library which provides a secure layer, over a reliable
    transport layer. Currently the GnuTLS library implements the proposed standards by the IETF's TLS working
    group.
    Security issues fixed with this release:
     CVE-2011-4128
    Buffer overflow in the gnutls_session_get_data function in lib/gnutls_session.c in GnuTLS 2.12.x before
    2.12.14 and 3.x before 3.0.7, when used on a client that performs nonstandard session resumption, allows
    remote TLS servers to cause a denial of service (application crash) via a large SessionTicket.
     CVE-2012-1573
    gnutls_cipher.c in libgnutls in GnuTLS before 2.12.17 and 3.x before 3.0.15 does not properly handle data
    encrypted with a block cipher, which allows remote attackers to cause a denial of service (heap memory
    corruption and application crash) via a crafted record, as demonstrated by a crafted GenericBlockCipher
    structure.

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