Description

Updated PXE packages are now available for Red Hat Linux which fix a vulnerability that can crash the PXE server using certain DHCP packets.

The PXE package contains the PXE (Preboot eXecution Environment) server and code needed for Linux to boot from a boot disk image on a Linux PXE server. It was found that the PXE server could be crashed using DHCP packets from some Voice Over IP (VOIP) phones. This bug could be used to cause a denial of service attack on remote systems by using malicious packets. Users of PXE are advised to upgrade to the new release which contains a version of PXE that is not vulnerable to this issue.
