Vulnerability Assessment Details

RHSA-2002-165: pxe

Vulnerability Assessment Summary
Check for the version of the pxe packages

Detailed Explanation for this Vulnerability Assessment


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.
