New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

A buffer underflow flaw was found in the way the uncompress utility of BusyBox expanded certain archive files compressed using Lempel-Ziv compression. If a user were tricked into expanding a specially crafted archive file with uncompress, it could cause BusyBox to crash or, potentially, execute arbitrary code with the privileges of the user running BusyBox. (CVE-2006-1168)

The BusyBox DHCP client, udhcpc, did not sufficiently sanitize certain options provided in DHCP server replies, such as the client hostname.
A malicious DHCP server could send such an option with a specially crafted value to a DHCP client. If this option's value was saved on the client system, and then later insecurely evaluated by a process that assumes the option is trusted, it could lead to arbitrary code execution with the privileges of that process. (CVE-2011-2716)

Solution

Run 'yum update busybox' to update your system.
