GLSA-201701-05 : BusyBox: Denial of Service
High Nessus Plugin ID 96236
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
A remote attacker might send a specially crafted package to a machine running BusyBox ntpd, possibly resulting in a Denial of Service condition.
There is no known workaround at this time.
SolutionAll BusyBox users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-apps/busybox-1.25.1'
