1. Overview:

Wind River has released a security advisory pertaining to their embedded version of Linux. This advisory contains vulnerabilities that may affect Avaya systems.

schpw.c in the kpasswd service in kadmind in MIT Kerberos 5 (aka krb5) before 1.11.3 does not properly validate UDP packets before sending responses, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged packet that triggers a communication loop, as demonstrated by krb_pingpong.nasl, a related issue to CVE-1999-0103. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2002-2443 to this issue.

No Avaya system products are vulnerable, as the affected packages from Wind River are not installed by default.
