Discussion
FreeBSD 'mount(2)' and 'nmount(2)' Multiple Stack Buffer Overflow Vulnerabilities
FreeBSD is prone to multiple stack-based buffer-overflow vulnerabilities because the kernel fails to perform adequate boundary checks on user-supplied data.
A local attacker can exploit these issues to execute arbitrary code with kernel-level privileges. Successfully exploiting these issues will result in the complete compromise of affected computers. Failed exploit attempts will cause a denial-of-service condition.
FreeBSD 7.0-RELEASE and 7.0-STABLE are vulnerable.
