- Updated PXE packages are now available for Red Hat Linux Advanced Server
- 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 (DoS) attack on remote systems by using malicious packets.
-
- Users of PXE on Red Hat Linux Advanced Server are advised to upgrade to the
- new release which contains a version of PXE that is not vulnerable to this
- issue.
