Vulnerability Details
CVEID: CVE-2017-14495
DESCRIPTION: dnsmasq is vulnerable to a denial of service, caused by a memory leak when the --add-mac, --add-cpe-id or --add-subnet option is specified. By using vectors related to DNS response creation, a remote attacker could exploit this vulnerability to consume available memory.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/132935 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2017-14494
DESCRIPTION: dnsmasq could allow a remote attacker to obtain sensitive information, caused by improper validation of requests. By sending specially-crafted DHCPv6 forwarded requests, a remote attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/132934 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2017-14496
DESCRIPTION: dnsmasq is vulnerable to a denial of service, caused by an integer underflow in the add_pseudoheader function. By sending a specially-crafted DNS request, a remote attacker could exploit this vulnerability to cause the service to crash.
