CVE-2014-8611

Status Candidate

Overview

The __sflush function in fflush.c in stdio in libc in FreeBSD 10.1 and the kernel in Apple iOS before 9 mishandles failures of the write system call, which allows context-dependent attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow) via a crafted application.

FreeBSD Security Advisory - stdio Buffer Overflow
Posted Dec 10, 2014
Site security.freebsd.org

FreeBSD Security Advisory - 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. 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.
