Hi all,

From time to time I am seeing some errors in my Zeek’s cluster like these:

/opt/zeek/share/zeek/base/protocols/krb/./main.zeek, line 175 2020-04-16T15:13:49.866557Z Reporter::ERROR no such index (KRB::cipher\_name[KRB::msg$ticket$cipher])

/opt/zeek/share/zeek/base/protocols/krb/./main.zeek, line 175 2020-04-16T14:37:05.530502Z Reporter::ERROR no such index (KRB::cipher\_name[KRB::msg$ticket$cipher])

What does it matter? I am using Zeek 3.0.5 …

Thanks for reporting that, it's a bug that could cause some incorrect  
analysis/processing of the associated connection or even minor memory  
leak over time in that Zeek version. Proposed patch is on the way  
here:
