The Apple Mac OS X byte_swap_sbin()
function contains an integer overflow vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code or cause a denial of service on a vulnerable system.
DMG files are disk images that can contain a variety of filesystems. Apple Mac OS X contains an integer overflow vulnerability in the byte_swap_bin()
function in the UFS filesystem handling code.
By convincing a user to mount a specially-crafted DMG file, such as by viewing a web page with Safari, a remote, unauthenticated attacker may be able to execute code with the privileges of the user or cause a denial-of-service condition. Note that it is reported that it is unlikely that code execution can take place as a result of this vulnerability.
