FreeBSD : FreeBSD -- Buffer overflow in stdio (74ded00e-6007-11e6-a6c3-14dae9d210b8)

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

A programming error in the standard I/O library's __sflush() function
could erroneously adjust the buffered stream's internal state even
when no write actually occurred in the case when write(2) system call
returns an error. Impact : The accounting mismatch would accumulate,
if the caller does not check for stream status and will eventually
lead to a heap buffer overflow.

Such overflows may lead to data corruption or the execution of
arbitrary code at the privilege level of the calling program.
