CVSS Base Vector:
AV:N/AC:L/Au:N/C:C/I:C/A:C

Technical Details:
The following Linux Distribution Package is affected: xorg-server CVE-2008-1377 The (1) SProcRecordCreateContext and (2) SProcRecordRegisterClients functions in the Record extension and the (3) SProcSecurityGenerateAuthorization function in the Security extension in the X server 1.4 in X.Org X11R7.3 allow context-dependent attackers to execute arbitrary code via requests with crafted length values that specify an arbitrary number of bytes to be swapped on the heap, which triggers heap corruption. CVE-2008-1379 Integer overflow in the fbShmPutImage function in the MIT-SHM extension in the X server 1.4 in X.Org X11R7.3 allows context-dependent attackers to read arbitrary process memory via crafted values for a Pixmap width and height. CVE-2008-2360 Integer overflow in the AllocateGlyph function in the Render extension in the X server 1.4 in X.Org X11R7.3 allows context-dependent attackers to execute arbitrary code via unspecified request fields that are used to calculate a heap buffer size, which triggers a heap-based buffer overflow. CVE-2008-2361 Integer overflow in the ProcRenderCreateCursor function in the Render extension in the X server 1.4 in X.Org X11R7.3 allows context-dependent attackers to cause a denial of service (daemon crash) via unspecified request fields that are used to calculate a glyph buffer size, which triggers a dereference of unmapped memory. CVE-2008-2362 Multiple integer overflows in the Render extension in the X server 1.4 in X.Org X11R7.3 allow context-dependent attackers to execute arbitrary code via a (1) SProcRenderCreateLinearGradient, (2) SProcRenderCreateRadialGradient, or (3) SProcRenderCreateConicalGradient request with an invalid field specifying the number of bytes to swap in the request data, which triggers heap memory corruption.

Recommendations:
Update your system with the appropriate patches or software upgrades. http://lists.freedesktop.org/archives/xorg/2008-June/036026.html http://secunia.com/advisories/30627/ http://www.vuxml.org/freebsd/800e8bd5-3acb-11dd-8842-001302a18722.html

Frequently Asked Questions

No, you can scan concurrently as many assets as you want. Please note that you must be aware of the hardware requeriments of the platform to ensure a good performance.

No, you can add as many assest as you want. It doesn't matters if you have millions of assets, we won't charge you for that.

No. The software is completely free. We have no intention to charge you to use the software, in fact - it completely goes against our beliefs and business model.

A vulnerability is defined in the ISO 27002 standard as “A weakness of an asset or group of assets that can be exploited by one or more threats” (International Organization for Standardization, 2005)

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
