Synopsis

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

Description

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.

Solution

Update the affected package.
