TITLE

Mac OS X and FreeBSD Kernel ufs_lookup Denial of service in function (DoS) Vulnerability

DESCRIPTION

The ufs_lookup function in the Mac OS X 10.4.8 and FreeBSD 6.1 kernels allows local users to cause a denial of service (kernel panic) and possibly corrupt other filesystems by mounting a crafted UNIX File System (UFS) DMG image that contains a corrupted directory entry (struct direct), related to the ufs_dirbad function. NOTE: a third party states that the FreeBSD issue does not cross privilege boundaries. Apple Mac OS X is prone to a remote denial-of-service vulnerability. This issue occurs when the UFS filesystem handler fails to handle specially crafted DMG images. A successful exploit can allow a remote attacker to cause kernel panic, resulting in a denial-of-service condition. Mac OS X 10.4.8 is vulnerable; other versions may also be affected. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German. The improvements will help our customers to get a better understanding of how we reached our conclusions, how it was rated, our thoughts on exploitation, attack vectors, and scenarios.

The vulnerability is caused due to an error in the fatfile_getarch2() function. This can be exploited to cause an integer overflow and may potentially allow execution of arbitrary code with kernel privileges via a specially crafted Mach-O Universal binary. Other versions may also be affected. SOLUTION: Grant only trusted users access to affected systems.
