Title: Apple Mac OS X 'i386_set_ldt' and '1386_get_ldt' Multiple Integer Overflow Vulnerabilities
Severity: HIGH
Description:
Apple Mac OS X is prone to multiple integer-overflow vulnerabilities because the software fails to perform adequate boundary checks on integer values. Specifically, the vulnerabilities affect the ' 'i386_set_ldt' and 'i386_get_ldt' kernel calls.
Local attackers can exploit these issues to execute arbitrary code with SYSTEM-level privileges. Successfully exploiting these issues will completely compromise an affected computer. Failed exploit attempts will likely crash the affected computer.
Apple Mac OS X 10.5 through 10.5.5 and Mac OS X Server 10.5 through 10.5.5 are vulnerable.
