TITLE

Apple Safari WebKit component vulnerable to buffer overflow

DESCRIPTION

Cross-site scripting (XSS) vulnerability in Syndication (Safari RSS) in Mac OS X 10.4 through 10.4.5 allows remote attackers to execute arbitrary JavaScript via unspecified vectors involving RSS feeds. Apple Safari is vulnerable to a stack-based buffer overflow. This may allow a remote attacker to execute arbitrary code on a vulnerable system. Apple has released Security Update 2006-001 to address multiple remote and local Mac OS X vulnerabilities. Apple has also released updates to address these issues. There is a directory traversal vulnerability in the implementation of this framework, which allows an attacker to decompress files to any location writable by the current user. If the user is logged on with administrative privileges, the attacker could take complete control of an affected system. Solution Since there is no known patch for this issue at this time, US-CERT is recommending a workaround. ---------------------------------------------------------------------- 2003: 2,700 advisories published 2004: 3,100 advisories published 2005: 4,600 advisories published 2006: 5,300 advisories published How do you know which Secunia advisories are important to you? The Secunia Vulnerability Intelligence Solutions allows you to filter and structure all the information you need, so you can address issues effectively. This can be exploited via a specially crafted email containing an attachment of an ostensibly safe file type (e.g. ".jpg") to execute arbitrary shell commands when the attachment is double-clicked. SOLUTION: Do not open attachments from untrusted sources. 1) Various security issues exist in the PHP Apache module and scripting environment. For more information: SA17371 2) An error in automount makes it possible for malicious file servers to cause a vulnerable system to mount file systems with reserved names, which can cause a DoS (Denial of Service) or potentially allow arbitrary code execution. 3) An input validation error in the BOM framework when unpacking certain archives can be exploited to cause files to be unpacked to arbitrary locations via directory traversal attacks. 4) The "passwd" program creates temporary files insecurely, which can be exploited via symlink attacks to create or overwrite arbitrary files with "root" privileges. 5) User directories are insecurely mounted when a FileVault image is created, which may allow unauthorised access to files. 6) An error in IPSec when handling certain error conditions can be exploited to cause a DoS against VPN connections. 7) An error in the LibSystem component can be exploited by malicious people to cause a heap-based buffer overflow via applications when requesting large amounts of memory. 8) The "Download Validation" in the Mail component fails to warn users about unsafe file types when an e-mail attachment is double-clicked. 9) In certain cases a Perl program may fail to drop privileges. For more information: SA17922 10) A boundary error in rsync can be exploited by authenticated users to cause a heap-based buffer overflow when it's allowed to transfer extended attributes. 11) A boundary error in WebKit's handling of certain HTML can be exploited to cause a heap-based buffer overflow. 12) A boundary error in Safari when parsing JavaScript can be exploited to cause a stack-based buffer overflow and allows execution of arbitrary code when a malicious web page including specially crafted JavaScript is viewed. 13) An error in Safari's security model when handling HTTP redirection can be exploited to execute JavaScript in the local domain via a specially crafted web site. 14) An error in Safari / LaunchServices may cause a malicious application to appear as a safe file type. This may cause a malicious file to be executed automatically when the "Open safe files after downloading" option is enabled. SOLUTION: Apply Security Update 2006-001.
