Details

An updated dhcpcd package that fixes a denial of service issue is
now available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

The dhcpcd package includes a DHCP client daemon.

An out of bounds memory read bug was found in dhcpcd. A malicious user on
the local network could send a specially crafted DHCP packet to the client
causing it to crash. The Common Vulnerabilities and Exposures project
assigned the name CAN-2005-1848 to this issue.

Users of dhcpcd should update to this erratum package, which contains a
patch that resolves this issue.
