high Nessus Plugin ID 111811

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

This update for libheimdal to version 7.5.0 fixes the following issues :

The following security vulnerability was fixed :

 - CVE-2017-17439: Fixed a remote denial of service vulnerability through which remote unauthenticated attackers were able to crash the KDC by sending a crafted UDP packet containing empty data fields for client name or realm (boo#1071675)

The following other bugs were fixed :

 - Override the build date (boo#1047218)

 - Use constant hostname (boo#1084909)

 - Handle long input lines when reloading database dumps

 - In pre-forked mode, correctly clear the process ids of exited children, allowing new child processes to replace the old.

 - Fixed incorrect KDC response when no-cross realm TGT exists, allowing client requests to fail quickly rather than time out after trying to get a correct answer from each KDC.

Solution

Update the affected libheimdal packages.
