Beskrivelse	Synopsis : The remote host is missing the DSA-2188 security update Description : 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 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. See also : http://www.debian.org/security/2011/dsa-2188 Solution : The Debian project recommends that you upgrade your webkit packages. Risk factor : Critical / CVSS Base Score : 10.0 (CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
