high Nessus Plugin ID 96236

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201701-05 (BusyBox: Denial of Service)

 The recv_and_process_client_pkt function in networking/ntpd.c in BusyBox allows remote attackers to cause a Denial of Service (CPU and bandwidth consumption) via a forged NTP packet, which triggers a communication loop.
 Impact :

 A remote attacker might send a specially crafted package to a machine running BusyBox ntpd, possibly resulting in a Denial of Service condition.
 Workaround :

 There is no known workaround at this time.

Solution

All BusyBox users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=sys-apps/busybox-1.25.1'
