Log4j, CVE-2021-44228, and Mahout

2021-12-13 Thread Trevor Grant
Many of you have probably become aware of Log4j's vulnerability to
CVE-2021-44228 recently.

Though Mahout is a sleepy project, we are vigilant and want you to know we
are aware of the issue and have been monitoring.

First, let me assure you that since Mahout (like over 90% of log4j users)
is on version 1.x it is not vulnerable to the JDNI remote execution attack
[1]. That said, 1.x was set for EOL in 2015, so it's probably time to
update that. I've made a JIRA ticket (MAHOUT-2140)[2].

The update isn't too complex, but it's also not trivial, and most
importantly it's not critical so you're not endangering anything running
Mahout, and we'll hopefully get it in for the next release in a couple of
months.

Hope this helps everyone feel secure going into their holiday season.

Thanks Trevor; may be a good time to revive our online meetings to talk
through this one..

I could find time during the holiday break pretty much any day; if anyone
else is interested let us know if there's a good time to chat.
