Software: Apple Safari 4.x

Description :
Some vulnerabilities have been reported in Apple Safari, which can be exploited by malicious people to disclose sensitive information, bypass certain security restrictions, or compromise a user's system.

1) A boundary error in ImageIO can be exploited to cause a buffer underflow and potentially execute arbitrary code via a specially crafted TIFF image.

2) An uninitialised memory access error in ImageIO when handling BMP images can be exploited to disclose certain data from the browser's memory.

3) An uninitialised memory access error in ImageIO when handling TIFF images can be exploited to disclose certain data from the browser's memory.

4) An error in ImageIO when processing TIFF images can be exploited to corrupt memory and potentially execute arbitrary code.

5) An error when viewing or updating RSS or Atom feeds can be exploited to bypass the "Accept Cookies" preference and set a cookie.

6) An error when handling external URL schemes can be exploited to open an arbitrary local file.

7) An error in WebKit when handling CSS "format()" arguments can be exploited to corrupt memory and potentially execute arbitrary code.

A use-after-free error in WebKit when handling HTML object element fallback content can be exploited to potentially execute arbitrary code.

9) An integer overflow error in ColorSync can be exploited to potentially execute arbitrary code via a specially crafted embedded color profile.

10) A use-after-free error in WebKit when parsing XML documents can be exploited to potentially execute arbitrary code.

11) A use-after-free error in WebKit when handling HTML elements containing right-to-left text can be exploited to potentially execute arbitrary code.

12) A use-after-free error in WebKit when handling nested HTML tags can be exploited to potentially execute arbitrary code.

13) An error when handling cross-origin stylesheet requests can be exploited to disclose data from another domain.

14) A use-after-free error in WebKit when handling callbacks for HTML elements can be exploited to potentially execute arbitrary code.

15) A use-after-free error in WebKit when rendering content with a CSS display property set to "run-in" can be exploited to potentially execute arbitrary code.

16) A use-after-free error in WebKit when handling HTML image elements can be exploited to potentially execute arbitrary code.

The vulnerabilities are reported in versions prior to 4.0.5.

Solution :
Update to version 4.0.5.

FURTHER>>>>>>>>>>>>>>>

Apple has released Safari 4.0.5, an update which addresses sixteen vulnerabilities in the browser, along with a number of stability and performance improvements.

>>>> Six of the flaws affect only Windows versions of Safari, with the remaining ten affecting both Mac OS X and Windows versions.<<<<<

The Windows only flaws include integer overflows when processing colour profiles, TIFF, or BMP images and the handling of external URLs, all of which could lead to arbitrary code execution.

Vulnerabilities in WebKit affect both Mac OS X and Windows versions of Safari. Most of these vulnerabilities can lead to crashing applications or arbitrary code execution. Use-after-free issues were found and addressed in the handling of the HTML object element, HTML elements with right to left text, parsing of XML documents, nested HTML tags, CSS rendering, and HTML callbacks. Memory corruption in CSS handling and errors in cross-origin handling were addressed. A bug which allowed cookies to be set, even if Safari was configured to block cookies, was also fixed.

Would seem safari needs some inoculations to enter the jungle!! S
