CVE-2016-2090 [CRITICAL] CVE-2016-2090 libbsd: heap buffer overflow in fgetwln function
CVE-2016-2090 libbsd: heap buffer overflow in fgetwln function
libbsd 0.8.1 and earlier contains a buffer overflow in the function
fgetwln(). An if checks if it is necessary to reallocate memory in the
target buffer. However this check is off by one, therefore an out of
bounds write happens.
