RedHat: Moderate: dhcpcd security update
Summary
Summary
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.
