Vigil@nce - Juniper Junos: denial of service via TCP Fragment
December 2015 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can send a malicious series of fragmented TCP packets
to a TCP service listening on Juniper Junos, in order to trigger a
denial of service.
Impacted products: Juniper J-Series, JUNOS.
Severity: 2/4.
Creation date: 15/10/2015.
DESCRIPTION OF THE VULNERABILITY
The Juniper Junos product reassembles received TCP fragmented
packets.
However, when a special sequence of fragmented packets is
received, Junos consumes all its resources.
An attacker can therefore send a malicious series of fragmented
TCP packets to a TCP service listening on Juniper Junos, in order
to trigger a denial of service.
