Description
This security bulletin contains information about 1 vulnerability.
1) Integer underflow (CVE-ID: CVE-2017-9214)
CWE-ID: CWE-191 - Integer underflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the Open vSwitch (OvS) component due to unsigned integer underflow in the function ofputil_pull_queue_get_config_reply10 in lib/ofp-util.c. when parsing of OFPT_QUEUE_GET_CONFIG_REPLY messages. A remote attacker can send a specially crafted OFPT_QUEUE_GET_CONFIG_REPLY message, trigger buffer over-read and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
