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.

For more information:
SA35515

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.

8) A use-after-free error in WebKit when destroying certain elements embedded inside "blink" containers 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 handling mouse events for an Anchor tag within 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 related to the "HTMLObjectElement::renderFallBackContent()" method can be exploited to trigger a memory corruption and 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.
