Title: dhcpcd: Multiple vulnerabilities (GLSA 201606-07)
Date: June 18, 2016
Multiple vulnerabilities have been found in dhcpcd allowing remote
attackers to possibly execute arbitrary code or cause a Denial of Service.
A fully featured, yet light weight RFC2131 compliant DHCP client
Vulnerable: < 6.10.0
Unaffected: >= 6.10.0
Architectures: All supported architectures
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.
All dhcpcd users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/dhcpcd-6.10.0”
