A vulnerability has been reported in Kerberos V5, which can be exploited by malicious, local users to perform certain actions on a vulnerable system with escalated privileges.

The vulnerability is caused due to the "send-pr.sh" script creating temporary files insecurely. This can be exploited via symlink attacks to create or overwrite arbitrary files with the privileges of the user invoking the vulnerable script.

The vulnerability has been reported in versions 1.3.4 and 1.3.5 for Linux. Other versions may also be affected.
