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

medium Nessus Plugin ID 92914

Language:

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.

Solution

Update the affected package.
