Some vulnerabilities have been reported in Apple Safari, which can be exploited by malicious people to bypass certain security restrictions, disclose sensitive information, conduct spoofing or cross-site scripting attacks, and potentially compromise a user's system.

1) An error when processing ColorSync profiles embedded in a specially crafted image can be exploited to potentially execute arbitrary code.

This is related to vulnerability #2 in:
SA36096

2) The browser follows links containing arbitrary user information without warning, which can be exploited to facilitate phishing attacks via specially crafted URLs.

3) A use-after-free error when handling PDF files can be exploited to potentially execute arbitrary code.

4) An error in WebKit when handling clipboard URLs can be exploited to disclose sensitive files if a user is tricked into dragging or pasting links or images to a malicious website.

5) An error in WebKit when a selection from a website is dragged or pasted into another website can be exploited to potentially execute arbitrary JavaScript code in the context of the destination website.

6) An error in WebKit when handling UTF-7 encoded text can be exploited to leave an HTML quoted string unterminated and facilitate cross-site scripting attacks.

7) An input sanitation error in WebKit when handling Local Storage and Web SQL databases can be exploited to create database files in arbitrary directories via directory traversal attacks.

8) A use-after-free error in WebKit when rendering HTML buttons can be exploited to potentially execute arbitrary code.

9) A use-after-free error in WebKit when handling attribute manipulations can be exploited to potentially execute arbitrary code.

10) An error in WebKit when handling HTML document fragments can be exploited to execute arbitrary JavaScript code in a legitimate context processing foreign HTML fragments.

11) An error in WebKit when handling keyboard focus can be exploited to deliver key press events intended for a different frame.

12) An error in WebKit when handling DOM constructor objects can be exploited to conduct cross-site scripting attacks.

18) A use-after-free error in WebKit when handling the ":first-letter" pseudo-element in cascading stylesheets can be exploited to potentially execute arbitrary code.

19) A double-free error in WebKit when handling event listeners in SVG documents can be exploited to potentially execute arbitrary code.

20) An uninitialised memory access error in WebKit when handling "use" elements in SVG documents can be exploited to potentially execute arbitrary code.

21) A use-after-free error in WebKit when handling SVG documents with recursive "use" elements can be exploited to potentially execute arbitrary code.

22) An error in WebKit when handling nested "use" elements in SVG documents can be exploited to corrupt memory and potentially execute arbitrary code.

23) A use-after-free error in WebKit when handling CSS run-ins can be exploited to potentially execute arbitrary code.

24) A use-after-free error in WebKit when handling HTML elements with custom vertical positioning can be exploited to potentially execute arbitrary code.

25) An error exists in WebKit when visiting HTTPS websites redirecting to HTTP websites. This can be exploited to disclose potentially sensitive information contained in the HTTPS URL by reading the "Referer" header.

26) An integer truncation error in WebKit when handling TCP requests can be exploited to pass arbitrary data to arbitrary TCP ports.

27) An error in WebKit when processing connections to IRC ports can be exploited to send arbitrary data to arbitrary IRC servers.

28) A use-after-free error in WebKit when handling hover events can be exploited to potentially execute arbitrary code.

29) An error in WebKit can be exploited to read NTLM credentials that are incorrectly transmitted in plain-text via Man-in-the-Middle (MitM) attacks.

30) A use-after-free error in WebKit when handling the "removeChild" DOM method can be exploited to potentially execute arbitrary code.

31) An error in WebKit when handling libxml contexts can be exploited to potentially execute arbitrary code.

32) An error in WebKit when handling a canvas with an SVG image pattern can be exploited to load and capture an image from another website.

33) An error in WebKit when rendering CSS-styled HTML content with multiple ":after" pseudo-selectors can be exploited to corrupt memory and potentially execute arbitrary code.

34) An error in WebKit when handling the "src" attribute of a frame element can be exploited to facilitate cross-site scripting attacks.

35) A use-after-free error in WebKit when handling drag and drop operations can be exploited to potentially execute arbitrary code.

36) An error in the implementation of the JavaScript "execCommand" function can be exploited to modify the contents of the clipboard.

37) An error when handling malformed URLs can be exploited to bypass the same-origin policy and execute arbitrary script code in the context of a different domain.

38) A use-after-free error in WebKit when handling DOM "Range" objects can be exploited to potentially execute arbitrary code.

39) A use-after-free error in WebKit when handling the "Node.normalize()" method can be exploited to potentially execute arbitrary code.

40) A use-after-free error in WebKit when rendering HTML document subtrees can be exploited to potentially execute arbitrary code.

41) An error in WebKit when handling HTML content in "textarea" elements can be exploited to conduct cross-site scripting attacks.

42) An error in WebKit when visiting a website which redirects form submissions to a redirecting website can be exploited disclose submitted data.

43) An error in WebKit when handling text transformations applied to elements having the IBM1147 character set can be exploited to potentially execute arbitrary code.

44) A use-after-free error in WebKit when handling fonts can be exploited to potentially execute arbitrary code.

45) An error in WebKit when handling HTML tables can be exploited to trigger an out-of-bounds memory access and potentially execute arbitrary code.

46) An error in WebKit when handling the CSS ":visited" pseudo-class can be exploited to disclose visited websites.

47) Multiple integer overflows when processing TIFF files can be exploited to cause a heap-based buffer overflow and potentially execute arbitrary code.
