Unspecified vulnerability in WebKit in Apple Safari before 3.1.2, as distributed in Mac OS X before 10.5.4, and standalone for Windows and Mac OS X 10.4, allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via vectors involving JavaScript arrays that trigger memory corruption.

This updated WebKit snapshot fixes CVE-2008-2307. (A memory corruption issue exists in WebKit's handling of JavaScript arrays. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution.)

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.

The version of Apple Safari installed on the remote host reportedly has a memory corruption issue in WebKit's handling of JavaScript arrays.

The remote host is running a version of Mac OS X 10.4 that does not have the security update 2008-004 applied. 

This update contains security fixes for a number of programs.

The remote host is running a version of Mac OS X 10.5.x that is prior to 10.5.4. 

Mac OS X 10.5.4 contains security fixes for multiple components.

The version of Safari installed on the remote host reportedly is affected by several issues :

  - An out-of-bounds memory read while handling BMP and GIF     images may lead to information disclosure     (CVE-2008-1573).

  - Safari will automatically launch executable files     downloaded from a site if that site is in an IE7 zone     with 'Launching applications and unsafe files' set to     'Enable' or an IE6 'Local intranet ' / ' Trusted sites'     zone (CVE-2008-2306).

  - There is a memory corruption issue in WebKit's     handling of JavaScript arrays that could be leveraged     to crash the application or execute arbitrary code     if visiting a malicious site (CVE-2008-2307).

  - When handling an object with an unrecognized content     type, Safari does not prompt the user before     downloading the object (aka, the 'carpet-bombing'     issue). If the download location is the Windows     Desktop (the default), this could lead to arbitrary     code execution (CVE-2008-2540).

The remote host is running a version of Mac OS X 10.5 that is older than version 10.5.4.  Mac OS X 10.5.4 contains security fixes for a number of programs.
