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

From Red Hat Security Advisory 2008:0503 :

Updated xorg-x11 packages that fix several security issues are now available for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The xorg-x11 packages contain X.Org, an open source implementation of the X Window System. It provides the basic low-level functionality that full-fledged graphical user interfaces are designed upon.

An input validation flaw was discovered in X.org's Security and Record extensions. A malicious authorized client could exploit this issue to cause a denial of service (crash) or, potentially, execute arbitrary code with root privileges on the X.Org server. (CVE-2008-1377)

Multiple integer overflow flaws were found in X.org's Render extension. A malicious authorized client could exploit these issues to cause a denial of service (crash) or, potentially, execute arbitrary code with root privileges on the X.Org server. (CVE-2008-2360, CVE-2008-2361)

An input validation flaw was discovered in X.org's MIT-SHM extension.
A client connected to the X.org server could read arbitrary server memory. This could result in the sensitive data of other users of the X.org server being disclosed. (CVE-2008-1379)

Users of xorg-x11 should upgrade to these updated packages, which contain backported patches to resolve these issues.

The remote host is affected by the vulnerability described in GLSA-200806-07 (X.Org X server: Multiple vulnerabilities)

    Regenrecht reported multiple vulnerabilities in various X server     extensions via iDefense:
    The     SProcSecurityGenerateAuthorization() and SProcRecordCreateContext()     functions of the RECORD and Security extensions are lacking proper     parameter validation (CVE-2008-1377).
    An integer overflow is     possible in the function ShmPutImage() of the MIT-SHM extension     (CVE-2008-1379).
    The RENDER extension contains several     possible integer overflows in the AllocateGlyph() function     (CVE-2008-2360) which could possibly lead to a heap-based buffer     overflow. Further possible integer overflows have been found in the     ProcRenderCreateCursor() function (CVE-2008-2361) as well as in the     SProcRenderCreateLinearGradient(), SProcRenderCreateRadialGradient()     and SProcRenderCreateConicalGradient() functions (CVE-2008-2362).
  Impact :

    Exploitation of these vulnerabilities could possibly lead to the remote     execution of arbitrary code with root privileges, if the server is     running as root, which is the default. It is also possible to crash the     server by making use of these vulnerabilities.
  Workaround :

    It is possible to avoid these vulnerabilities by disabling the affected     server extensions. Therefore edit the configuration file     (/etc/X11/xorg.conf) to contain the following in the appropriate     places:
      Section 'Extensions'     	Option 'MIT-SHM' 'disable'     	Option 'RENDER' 'disable'     	Option 'SECURITY' 'disable'       EndSection       Section 'Module'        Disable 'record'       EndSection

Updated XFree86 packages that fix several security issues are now available for Red Hat Enterprise Linux 3.

This update has been rated as having important security impact by the Red Hat Security Response Team.

XFree86 is an implementation of the X Window System, which provides the core functionality for the Linux graphical desktop.

An input validation flaw was discovered in X.org's Security and Record extensions. A malicious authorized client could exploit this issue to cause a denial of service (crash) or, potentially, execute arbitrary code with root privileges on the X.Org server. (CVE-2008-1377)

Multiple integer overflow flaws were found in X.org's Render extension. A malicious authorized client could exploit these issues to cause a denial of service (crash) or, potentially, execute arbitrary code with root privileges on the X.Org server. (CVE-2008-2360, CVE-2008-2361)

An input validation flaw was discovered in X.org's MIT-SHM extension.
A client connected to the X.org server could read arbitrary server memory. This could result in the sensitive data of other users of the X.org server being disclosed. (CVE-2008-1379)

Users of XFree86 are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple flaws were found in the RENDER, RECORD, and Security extensions of X.org which did not correctly validate function arguments. An authenticated attacker could send specially crafted requests and gain root privileges or crash X. (CVE-2008-1377, CVE-2008-2360, CVE-2008-2361, CVE-2008-2362)

It was discovered that the MIT-SHM extension of X.org did not correctly validate the location of memory during an image copy. An authenticated attacker could exploit this to read arbitrary memory locations within X, exposing sensitive information. (CVE-2008-1379).
