CVE-2011-1774

TITLE

Apple Safari Used in WebKit Vulnerable to arbitrary file creation

DESCRIPTION

WebKit in Apple Safari before 5.0.6 has improper libxslt security settings, which allows remote attackers to create arbitrary files, and consequently execute arbitrary code, via a crafted web site. NOTE: this may overlap CVE-2011-1425. WebKit is prone to a remote code-execution vulnerability. Failed exploit attempts will crash the application. NOTE: This issue was previously discussed in BID 48808 (Apple Safari Prior to 5.1 and 5.0.6 Multiple Security Vulnerabilities) but has been given its own record to better document it. WebKit is a set of open source web browser engines jointly developed by companies such as KDE, Apple (Apple), and Google (Google), and is currently used by browsers such as Apple Safari and Google Chrome. ---------------------------------------------------------------------- The Secunia Vulnerability Intelligence Manager (VIM) enables you to handle vulnerability threats in a simple, cost effective way.

This can lead to certificates signed by the disabled root certificates being validated. 4) An integer overflow error exists within the ColorSync component. For more information see vulnerability #5 in: SA45054 5) An off-by-one error exists within the CoreFoundation framework. For more information see vulnerability #6 in: SA45054 6) An integer overflow error exists in CoreGraphics. For more information see vulnerability #7 in: SA45054 7) An error exists within ICU (International Components for Unicode). For more information see vulnerability #11 in: SA45054 8) An error exists in ImageIO within the handling of TIFF files when handling certain uppercase strings. For more information see vulnerability #9 in: SA45054 9) An error in ImageIO within the handling of CCITT Group 4 encoded TIFF image files can be exploited to cause a heap-based buffer overflow. 10) A use-after-free error within WebKit when handling TIFF images can result in an invalid pointer being dereferenced when a user views a specially crafted web page. 11) An error within libxslt can be exploited to disclose certain addresses from the heap. For more information see vulnerability #2 in: SA43832 12) An off-by-one error within libxml when handling certain XML data can be exploited to cause a heap-based buffer overflow. 13) An error in the "AutoFill web forms" feature can be exploited to disclose certain information from the user's Address Book by tricking a user into visiting a specially crafted web page. 14) A cross-origin error when handling certain fonts in Java Applets can lead to certain text being displayed on other sites. 15) Multiple unspecified errors in the WebKit component can be exploited to corrupt memory. 17) A cross-origin error when handling Web Workers can lead to certain information being disclosed. 18) A cross-origin error when handling certain URLs containing a username can be exploited to execute arbitrary HTML and script code in a user's browser session in the context of an affected site. 19) A cross-origin error when handling DOM nodes can be exploited to execute arbitrary HTML and script code in a user's browser session in the context of an affected site. 20) An error within the handling of DOM history objects can be exploited to display arbitrary content while showing the URL of a trusted web site in the address bar. 21) An error within the handling of RSS feeds may lead to arbitrary files from a user's system being sent to a remote server. 22) A weakness in WebKit can lead to remote DNS prefetching For more information see vulnerability #6 in: SA42312 23) A use-after-free error within WebKit when processing MathML markup tags can result in an invalid pointer being dereferenced when a user views a specially crafted web page. 24) An error within WebKit when parsing a frameset element can be exploited to cause a heap-based buffer overflow. 25) A use-after-free error within WebKit when handling XHTML tags can result in an invalid tag pointer being dereferenced when a user views a specially crafted web page. 26) A use-after-free error within WebKit when handling SVG tags can result in an invalid pointer being dereferenced when a user views a specially crafted web page. The weakness and the vulnerabilities are reported in versions prior to 5.1 and 5.0.6. SOLUTION: Update to version 5.1 or 5.0.6.
