Description

This security bulletin contains information about 1 vulnerability.


1) Buffer overflow (CVE-ID: CVE-2016-2074)

CWE-ID: CWE-120 - Buffer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists in lib/flow.c in ovs-vswitchd due to boundary error. A remote attacker can send specially crafted MPLS packets, as demonstrated by a long string in an ovs-appctl command, and execute arbitrary code.
