The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2005:420 advisory.

    The Linux kernel handles the basic functions of the operating system.

    This is the first regular kernel update to Red Hat Enterprise Linux 4.

    A flaw affecting the auditing code was discovered.  On Itanium     architectures a local user could use this flaw to cause a denial of service     (crash).  This issue is rated as having important security impact     (CAN-2005-0136).

    A flaw was discovered in the servicing of a raw device ioctl.  A local user     who has access to raw devices could use this flaw to write to kernel memory     and cause a denial of service or potentially gain privileges.  This issue     is rated as having moderate security impact (CAN-2005-1264).

    A flaw in fragment forwarding was discovered that affected the netfilter     subsystem for certain network interface cards. A remote attacker could send     a set of bad fragments and cause a denial of service (system crash). Acenic     and SunGEM network interfaces were the only adapters affected, which are in     widespread use. (CAN-2005-0209)

    A flaw in the futex functions was discovered affecting the Linux 2.6     kernel.  A local user could use this flaw to cause a denial of service     (system crash). (CAN-2005-0937)

    New features introduced by this update include:
    - Fixed TCP BIC congestion handling.
    - Diskdump support for more controllers (megaraid, SATA)
    - Device mapper multipath support
    - AMD64 dual core support.
    - Intel ICH7 hardware support.

    There were many bug fixes in various parts of the kernel.  The ongoing     effort to resolve these problems has resulted in a marked improvement     in the reliability and scalability of Red Hat Enterprise Linux 4.

    The following device drivers have been upgraded to new versions:
     ata_piix -------- 1.03      bonding --------- 2.6.1      e1000 ----------- 5.6.10.1-k2-NAPI      e100 ------------ 3.3.6-k2-NAPI      ibmveth --------- 1.03      libata ---------- 1.02 to 1.10      lpfc ------------ 0:8.0.16 to 0:8.0.16.6_x2      megaraid_mbox --- 2.20.4.0 to 2.20.4.5      megaraid_mm ----- 2.20.2.0-rh1 to 2.20.2.5      sata_nv --------- 0.03 to 0.6      sata_promise ---- 1.00 to 1.01      sata_sil -------- 0.8      sata_sis -------- 0.5      sata_svw -------- 1.05      sata_sx4 -------- 0.7      sata_via -------- 1.0      sata_vsc -------- 1.0      tg3 ------------- 3.22-rh      ipw2100 --------- 1.0.3      ipw2200 --------- 1.0.0

    All Red Hat Enterprise Linux 4 users are advised to upgrade their     kernels to the packages associated with their machine architectures     and configurations as listed in this erratum.

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.
