WebKit in Apple Safari before 4.0 does not properly initialize memory for Attr DOM objects, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted HTML document.

Various bugs in webkit have been fixed. The CVE id's are :

  - CVE-2009-1687     The JavaScript garbage collector in WebKit, as used in     qt4-x11 does not properly handle allocation failures,     which allows remote attackers to execute arbitrary code     or cause a denial of service (memory corruption and     application crash) via a crafted HTML document that     triggers write access to an 'offset of a NULL pointer.

  - CVE-2009-1690     Use-after-free vulnerability in WebKit, as used in     qt4-x11, allows remote attackers to execute arbitrary     code or cause a denial of service (memory corruption and     application crash) by setting an unspecified property of     an HTML tag that causes child elements to be freed and     later accessed when an HTML error occurs.

  - CVE-2009-1698     WebKit in qt4-x11 does not initialize a pointer during     handling of a Cascading Style Sheets (CSS) attr function     call with a large numerical argument, 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-2009-1699     The XSL stylesheet implementation in WebKit, as used in     qt4-x11 does not properly handle XML external entities,     which allows remote attackers to read arbitrary files     via a crafted DTD.

  - CVE-2009-1711     WebKit in qt4-x11 does not properly initialize memory     for Attr DOM objects, which allows remote attackers to     execute arbitrary code or cause a denial of service     (application crash) via a crafted HTML document.

  - CVE-2009-1712     WebKit in qt4-x11 does not prevent remote loading of     local Java applets, which allows remote attackers to     execute arbitrary code, gain privileges, or obtain     sensitive information via an APPLET or OBJECT element.

  - CVE-2009-1713     The XSLT functionality in WebKit, as used in qt4-x11     does not properly implement the document function, which     allows remote attackers to read arbitrary local files     and files from different security zones.

  - CVE-2009-1725     WebKit in qt4-x11 does not properly handle numeric     character references, 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-2009-2700     qt4-x11 does not properly handle a '\0' character in a     domain name in the Subject Alternative Name field of an     X.509 certificate, which allows man-in-the-middle     attackers to spoof arbitrary SSL servers via a crafted     certificate issued by a legitimate Certification     Authority.

The oldstable distribution (etch) is not affected by these problems.

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-2009-0945     Array index error in the insertItemBefore method in     WebKit, allows remote attackers to execute arbitrary     code via a document with a SVGPathList data structure     containing a negative index in the SVGTransformList,     SVGStringList, SVGNumberList, SVGPathSegList,     SVGPointList, or SVGLengthList SVGList object, which     triggers memory corruption.

  - CVE-2009-1687     The JavaScript garbage collector in WebKit does not     properly handle allocation failures, which allows remote     attackers to execute arbitrary code or cause a denial of     service (memory corruption and application crash) via a     crafted HTML document that triggers write access to an     'offset of a NULL pointer.'

  - CVE-2009-1690     Use-after-free vulnerability in WebKit, allows remote     attackers to execute arbitrary code or cause a denial of     service (memory corruption and application crash) by     setting an unspecified property of an HTML tag that     causes child elements to be freed and later accessed     when an HTML error occurs, related to 'recursion in     certain DOM event handlers.'

  - CVE-2009-1698     WebKit does not initialize a pointer during handling of     a Cascading Style Sheets (CSS) attr function call with a     large numerical argument, 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-2009-1711     WebKit does not properly initialize memory for Attr DOM     objects, which allows remote attackers to execute     arbitrary code or cause a denial of service (application     crash) via a crafted HTML document.

  - CVE-2009-1712     WebKit does not prevent remote loading of local Java     applets, which allows remote attackers to execute     arbitrary code, gain privileges, or obtain sensitive     information via an APPLET or OBJECT element.

  - CVE-2009-1725     WebKit do not properly handle numeric character     references, 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-2009-1714     Cross-site scripting (XSS) vulnerability in Web     Inspector in WebKit allows user-assisted remote     attackers to inject arbitrary web script or HTML, and     read local files, via vectors related to the improper     escaping of HTML attributes.

  - CVE-2009-1710     WebKit allows remote attackers to spoof the browser's     display of the host name, security indicators, and     unspecified other UI elements via a custom cursor in     conjunction with a modified CSS3 hotspot property.

  - CVE-2009-1697     CRLF injection vulnerability in WebKit allows remote     attackers to inject HTTP headers and bypass the Same     Origin Policy via a crafted HTML document, related to     cross-site scripting (XSS) attacks that depend on     communication with arbitrary websites on the same server     through use of XMLHttpRequest without a Host header.

  - CVE-2009-1695     Cross-site scripting (XSS) vulnerability in WebKit     allows remote attackers to inject arbitrary web script     or HTML via vectors involving access to frame contents     after completion of a page transition.

  - CVE-2009-1694     WebKit does not properly handle redirects, which allows     remote attackers to read images from arbitrary websites     via vectors involving a CANVAS element and redirection,     related to a 'cross-site image capture issue.'

  - CVE-2009-1681     WebKit does not prevent websites from loading     third-party content into a subframe, which allows remote     attackers to bypass the Same Origin Policy and conduct     'clickjacking' attacks via a crafted HTML document.

  - CVE-2009-1684     Cross-site scripting (XSS) vulnerability in WebKit     allows remote attackers to inject arbitrary web script     or HTML via an event handler that triggers script     execution in the context of the next loaded document.

  - CVE-2009-1692     WebKit allows remote attackers to cause a denial of     service (memory consumption or device reset) via a web     page containing an HTMLSelectElement object with a large     length attribute, related to the length property of a     Select object.

It was discovered that QtWebKit did not properly handle certain SVGPathList data structures. If a user were tricked into viewing a malicious website, an attacker could exploit this to execute arbitrary code with the privileges of the user invoking the program.
(CVE-2009-0945)

Several flaws were discovered in the QtWebKit browser and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program.
(CVE-2009-1687, CVE-2009-1690, CVE-2009-1698, CVE-2009-1711, CVE-2009-1725)

It was discovered that QtWebKit did not properly handle certain XSL stylesheets. If a user were tricked into viewing a malicious website, an attacker could exploit this to read arbitrary local files, and possibly files from different security zones. (CVE-2009-1699, CVE-2009-1713)

It was discovered that QtWebKit did not prevent the loading of local Java applets. If a user were tricked into viewing a malicious website, an attacker could exploit this to execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-1712).

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