Vulnerability Note VU#552136
Apple Mac OS X UFS filesystem integer overflow vulnerability
There is an integer overflow in the ffs_mountfs() function, which is used by Apple's OS X operating system to handle UFS disc images.
There is an integer overflow error in the ffs_mountfs() function that may occur when an OS X system opens a UFS disc image. To trigger the overflow, an attacker would need to convince a user to open a specially crafted disc image. Note that the Safari web browser's default settings consider UFS disc images to be a safe file type, and will automatically open them after downloading.
A remote, unauthenticated attacker with the ability to supply a specially crafted DMG file may be able to cause an affected system to crash, thereby creating a denial of service. The original reporter states that an attacker may also be able to execute arbitrary code using this vulnerability. However, this has not been confirmed.
