CVE Author: NIST National Vulnerability Database

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

Technical Details:
Several vulnerabilities have been discovered in webkit, a Web content engine library for Gtk+. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2010-1783 WebKit does not properly handle dynamic modification of a text node, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document. CVE-2010-2901 The rendering implementation in WebKit allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors. CVE-2010-4199 WebKit does not properly perform a cast of an unspecified variable during processing of an SVG use element, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted SVG document. CVE-2010-4040 WebKit does not properly handle animated GIF images, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted image. CVE-2010-4492 Use-after-free vulnerability in WebKit allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors involving SVG animations. CVE-2010-4493 Use-after-free vulnerability in Webkit allows remote attackers to cause a denial of service via vectors related to the handling of mouse dragging events CVE-2010-4577 The CSSParser::parseFontFaceSrc function in WebCore/css/CSSParser.cpp in WebKit does not properly parse Cascading Style Sheets (CSS) token sequences, which allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted local font, related to Type Confusion. CVE-2010-4578 WebKit does not properly perform cursor handling, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that lead to stale pointers. CVE-2011-0482 WebKit does not properly perform a cast of an unspecified variable during handling of anchors, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted HTML document CVE-2011-0778 WebKit does not properly restrict drag and drop operations, which might allow remote attackers to bypass the Same Origin Policy via unspecified vectors. For the stable distribution (squeeze), these problems have been fixed in version 1.2.7-0+squeeze1 For the testing distribution (wheezy), and the unstable distribution (sid), these problems have been fixed in version 1.2.7-1 Security support for WebKit has been discontinued for the oldstable distribution (lenny). The current version in oldstable is not supported by upstream anymore and is affected by several security issues. Backporting fixes for these and any future issues has become unfeasible and therefore we need to drop our security support for the version in oldstable.

Recommendations:
We recommend that you upgrade your webkit Linux Distribution Packages.

Summary:
The remote host is missing an update to webkit announced via advisory DSA 2188-1.

Detection Type:
Linux Distribution Package

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".
