CVE-2003-0795  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade quagga/quagga to version 0.96.4 or higher.

Overview

Affected versions of this package are vulnerable to Improper Input Validation. The vty layer in Quagga before 0.96.4, and Zebra 0.93b and earlier, does not verify that sub-negotiation is taking place when processing the SE marker, which allows remote attackers to cause a denial of service (crash) via a malformed telnet command to the telnet CLI port, which may trigger a null dereference.
