Name of the Vulnerable Software and Affected Versions mit-krb5 versions prior to 1.11.4

Description The issue affects the mit-krb5 package in Gentoo Linux, potentially leading to breaches of confidentiality, integrity, and availability of protected information. Exploitation can be done remotely. Specifically, in the kpasswd service in kadmind, schpw.c does not properly validate UDP packets before sending responses, allowing remote attackers to cause a denial of service by triggering a communication loop with forged packets.

Recommendations For versions prior to 1.11.4, update to version 1.11.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the kpasswd service in kadmind to minimize the risk of exploitation. Avoid using the vulnerable schpw.c in the kpasswd service until the issue is resolved.
