FreeBSD : FreeBSD -- iconv(3) NULL pointer dereference and out-of-bounds array access (6f91a709-6007-11e6-a6c3-14dae9d210b8)

Medium Nessus Plugin ID 92904


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


A NULL pointer dereference in the initialization code of the HZ module and an out of bounds array access in the initialization code of the VIQR module make iconv_open(3) calls involving HZ or VIQR result in an application crash. Impact : Services where an attacker can control the arguments of an iconv_open(3) call can be caused to crash resulting in a denial-of-service. For example, an email encoded in HZ may cause an email delivery service to crash if it converts emails to a more generic encoding like UTF-8 before applying filtering rules.


Update the affected package.
