Title: Multiple BSD Platforms 'strfmon()' Function Integer Overflow Weakness
Severity: CRITICAL
Description:
Multiple BSD platforms are prone to an integer-overflow weakness because the software fails to ensure that integer values are not overrun. The weakness occurs in the 'strfmon()' function located in the 'libc' library.
Attackers can exploit this issue through PHP using the 'money_format()' function.
Successful exploits will allow arbitrary code to run within the context of the affected software. Failed exploit attempts will result in a denial-of-service condition.
This issue affects FreeBSD 6, 7 and NetBSD 4; other platforms may also be affected.
