TITLE

Apple Safari of WebKit Vulnerable to arbitrary code execution

DESCRIPTION

Use-after-free vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to the Cascading Style Sheets (CSS) run-in property and multiple invocations of a destructor for a child element that has been referenced multiple times. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari's Webkit. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the application's support of the run-in display property. On insertion of a specific element with the "run-in" display property, the application will create a duplicate reference of a child element used to support that attribute. Upon destruction of the parent container, the application will then call the destructor for this child element multiple times. Successful exploitation can lead to code execution under the context of the application. Safari is prone to multiple security vulnerabilities that have been addressed in Apple security advisory APPLE-SA-2010-06-07-1. These issues affect versions prior to Safari 5.0 and 4.1 running on Apple Mac OS X, Windows 7, XP and Vista. Attackers can exploit these issues by enticing an unsuspecting user into visiting a malicious webpage. Successful attacks may result in information-disclosure, remote code-execution, denial-of-service, or other consequences. This BID is being retired. ---------------------------------------------------------------------- Secunia CSI integrated with Microsoft WSUS and Microsoft SCCM for 3rd party Patch Management Free webinars http://secunia.com/vulnerability_scanning/corporate/webinars/ ---------------------------------------------------------------------- TITLE: Apple Safari Multiple Vulnerabilities SECUNIA ADVISORY ID: SA40105 VERIFY ADVISORY: Secunia.com http://secunia.com/advisories/40105/ Customer Area (Credentials Required) https://ca.secunia.com/?page=viewadvisory&vuln_id=40105 RELEASE DATE: 2010-06-09 DISCUSS ADVISORY: http://secunia.com/advisories/40105/#comments AVAILABLE ON SITE AND IN CUSTOMER AREA: * Last Update * Popularity * Comments * Criticality Level * Impact * Where * Solution Status * Operating System / Software * CVE Reference(s) http://secunia.com/advisories/40105/ ONLY AVAILABLE IN CUSTOMER AREA: * Authentication Level * Report Reliability * Secunia PoC * Secunia Analysis * Systems Affected * Approve Distribution * Remediation Status * Secunia CVSS Score * CVSS https://ca.secunia.com/?page=viewadvisory&vuln_id=40105 ONLY AVAILABLE WITH SECUNIA CSI AND SECUNIA PSI: * AUTOMATED SCANNING http://secunia.com/vulnerability_scanning/personal/ http://secunia.com/vulnerability_scanning/corporate/wsus_sccm_3rd_third_party_patching/ DESCRIPTION: 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. 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. 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. 16) An uninitialised memory access error in WebKit when handling selection changes on form input elements 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. 22) An error in WebKit when handling nested "use" elements in SVG documents can be exploited to corrupt memory and 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. 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. 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. 36) An error in the implementation of the JavaScript "execCommand" function can be exploited to modify the contents of the clipboard. 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. 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. SOLUTION: Update to version 4.1 (available only for Mac OS X v10.4 systems) or upgrade to version 5.0.
