<title>dhcpcd: Multiple vulnerabilities</title>
<synopsis>Multiple vulnerabilities have been found in dhcpcd allowing remote
attackers to possibly execute arbitrary code or cause a Denial of Service.

<package name="net-misc/dhcpcd" auto="yes" arch="*">
<unaffected range="ge">6.10.0</unaffected>
<vulnerable range="lt">6.10.0</vulnerable>
<p>A fully featured, yet light weight RFC2131 compliant DHCP client</p>
<p>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.
<impact type="normal">
<p>Remote attackers could possibly execute arbitrary code with the
privileges of the process or cause Denial of Service.
<p>There is no known workaround at this time.</p>
<p>All dhcpcd users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-misc/dhcpcd-6.10.0”
