"The remote MiracleLinux 3 host has a package installed that is affected by multiple vulnerabilities as referenced in the
AXSA:2008-87:01 advisory.

    rdesktop is an open source client for Microsoft Windows NT Terminal Server and Microsoft Windows 2000 and
    2003 Terminal Services, capable of natively using the  Remote Desktop Protocol (RDP) to present the user's
    NT desktop. No additional server extensions are required.
    CVE-2008-1801: Integer underflow in the iso_recv_msg function (iso.c) in rdesktop 1.5.0 allows remote
    attackers to cause a denial of service (crash) and possibly execute arbitrary code via a Remote Desktop
    Protocol (RDP) request with a small length field.
    CVE-2008-1803: Integer signedness error in the xrealloc function (rdesktop.c) in RDesktop 1.5.0 allows
    remote attackers to execute arbitrary code via unknown parameters that trigger a heap-based overflow.
    NOTE: the role of the channel_process function was not specified by the original researcher.

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

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