Title: PXE Server Remote Buffer Overrun Vulnerability
Severity: CRITICAL
Description:
Red Hat Linux includes a Preboot eXecution Environment (PXE) server. PXE can be used to boot a Linux based system from a remote disk image.
A vulnerability has been discovered in PXE which is included with Red Hat Linux. Specifically, it is possible for a remote attacker to overrun a buffer by passing 10000 bytes of data to the service. This may result in the corruption of sensitive process memory, such as a saved instruction pointer, and as such may allow an attacker to execute arbitrary commands.
Successful exploitation of this issue could allow an attacker to execute commands with root privileges.
This issue has been reported to exist in PXE 2.0 Beta-1 on Red Hat Linux. Other versions may also be affected by this vulnerability.
Affected Products:
- RedHat PXE Server 2.0.0 Beta 1
