TITLE

Apple Mac OS X of XNU Kernel memory overwrite and privilege escalation vulnerability

DESCRIPTION

XNU 1228.9.59 and earlier on Apple Mac OS X 10.5.6 and earlier does not properly restrict interaction between user space and the HFS IOCTL handler, which allows local users to overwrite kernel memory and gain privileges by attaching an HFS+ disk image and performing certain steps involving HFS_GET_BOOT_INFO fcntl calls. Apple Mac OS X is prone to a local privilege-escalation vulnerability. A local attacker can exploit this issue to execute arbitrary code with elevated privileges. The following are vulnerable; other versions may also be affected. Mac OS X 10.4.8 through 10.4.11 Mac OS X 10.5.0 through 10.5.6. 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.

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. 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.
