GLSA-201606-07 : dhcpcd: Multiple vulnerabilities
Critical Nessus Plugin ID 91701
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201606-07 (dhcpcd: Multiple vulnerabilities)
A heap overflow can be triggered via malformed DHCP responses in the print_option (via dhcp_envoption1) due to incorrect option length values.
These vulnerabilities could also allow remote attackers to trigger an invalid read/crash via malformed DHCP responses.
Remote attackers could possibly execute arbitrary code with the privileges of the process or cause Denial of Service.
There is no known workaround at this time.
SolutionAll dhcpcd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/dhcpcd-6.10.0”
