CVE-2009-1727

TITLE

Apple Mac OS of CoreTypes Any of the blacklists in JavaScript Vulnerability to be executed

DESCRIPTION

Incomplete blacklist vulnerability in CoreTypes in Apple Mac OS X 10.5 before 10.5.8 makes it easier for user-assisted remote attackers to execute arbitrary JavaScript via a web page that offers a download with a Content-Type value that is not on the list of possibly unsafe content types for Safari. Apple Mac OS X is prone to multiple security vulnerabilities that have been addressed in Security Update 2009-003. The update addresses new vulnerabilities that affect the CFNetwork, ColorSync, CoreTypes, Dock, Image RAW, ImageIO, launchd, Login Window, MobileMe, Kernel, and XQuery components of Mac OS X. The advisory also contains security updates for seven previously reported issues. A list of system content types that will be marked as unsafe in certain circumstances (such as when downloading from a web page). I. II. Impact The impact of these vulnerabilities vary. Potential consequences include arbitrary code execution, sensitive information disclosure, denial of service, or privilege escalation. III. These and other updates are available via Software Update or via Apple Downloads. IV.

(Vulnerability Assessment Remediation Management) If not, then implement it through the most reliable vulnerability intelligence source on the market. Implement it through Secunia. 1) An error in bzip2 can be exploited to terminate an application using the library via a specially crafted archive. For more information: SA29410 2) An error in CFNetwork can be exploited by a malicious website to control the URL displayed in a certificate warning when Safari follows a redirect from a trusted website. 3) An error when processing ColorSync profiles embedded in a specially crafted image can be exploited to cause a heap-based buffer overflow and potentially execute arbitrary code. 4) An error when handling unsafe content types can be exploited to execute a malicious JavaScript payload when a specially crafted file is manually opened. 5) An error when processing four-finger Multi-Touch gestures can be exploited by a person with physical access to a locked system to manage applications or use Expose. NOTE: This vulnerability only affects system having a Multi-Touch trackpad. 6) An error when processing Canon RAW images can be exploited to cause a stack-based buffer overflow and potentially execute arbitrary code. 7) An error in ImageIO when processing OpenEXR images can be exploited to cause a heap-based buffer overflow and potentially execute arbitrary code. 8) Multiple errors in ImageIO when processing OpenEXR images can be exploited to corrupt memory and potentially execute arbitrary code. For more information: SA36030 9) A boundary error in ImageIO when processing EXIF metadata can be exploited to cause a buffer overflow and potentially execute arbitrary code via a specially crafted image. 10) An error in ImageIO when processing PNG images can be exploited to dereference an uninitialised pointer and potentially execute arbitrary code. 11) An error in the "fcntl()" kernel implementation can be exploited to corrupt kernel memory and execute arbitrary code with system privileges via e.g. a specially crafted TIOCGWINSZ "fnctl()" call. 12) An error in launchd when servicing via inetd can be exploited to cause a service hang by opening an overly large number of connections. 13) A format string error in Login Window when handling application names can be exploited to potentially execute arbitrary code. 14) The MobileMe preference pane fails to properly delete all credentials when signing out. This can be exploited to access previously signed in systems from the same local user account. 15) An error in the kernel when processing AppleTalk response packets can be exploited to cause a buffer overflow and potentially execute arbitrary code with system privileges. 16) A synchronization error when sharing file descriptors over local sockets can be exploited to cause an unexpected system shutdown. 17) A boundary error in the PCRE library used by XQuery can be exploited to cause a buffer overflow and potentially execute arbitrary code. of Johns Hopkins University, HiNRG The vendor also credits: 2) Kevin Day of Your.Org and Jason Mueller of Indiana University 4) Brian Mastenbrook, and Clint Ruoho of Laconic Security 6) Chris Ries of Carnegie Mellon University Computing Services 7) Lurene Grenier of Sourcefire VRT, and Chris Ries of Carnegie Mellon University Computing Services 10) Tavis Ormandy of the Google Security Team 13) Alfredo Pesoli of 0xcafebabe.it 15) Ilja van Sprundel from IOActive 16) Bennet Yee of Google Inc.
