I'm on an EC2 instance running RHEL 6.4. I found this problem in both 2.5.3 and an all-green-on-RHEL version of mongo from last night
$ mongod --version db version v2.5.4-pre- 2013-10-30T10:09:30.158-0400 git version: 97c3a3d2b487e9376d484d33ede2895e379a3033 modules: enterprise 2013-10-30T10:09:30.159-0400 OpenSSL version: OpenSSL 1.0.0-fips 29 Mar 2010
------------------------------------------------------------------------------
Briefly: I start a standalone mongod with audit logging. I create a
userAdminAnyDatabase-enabled user, log in as that user, create a new user "oo"
in a different database, and then try to update that user with customData.
The server crashes on the update.
In detail:
First, start a mongod, with this script:
rm -r /tmp/mongoda mkdir /tmp/mongoda mongod --port 27017 --logpath /tmp/mongoda/mongo.log --logappend --auditLog bsonfile --auth --auditPath /tmp/mongoda/audit.log --dbpath /tmp/mongoda --smallfiles --nopreallocj
Then, do this in the shell, or put it into a file boom.js and run it with
mongo boom.js:
db = db.getMongo().getDB('admin')
db.addUser({user:"uu", pwd:"pp", roles:["userAdminAnyDatabase", "clusterAdmin", "readWriteAnyDatabase", "dbAdminAnyDatabase"]})
db.auth("uu","pp")
db = db.getMongo().getDB('oink')
db.addUser({user:"oo", pwd:"pp", roles:["userAdmin", "readWrite", "dbAdmin"]})
db.runCommand({updateUser: "oo", customData:{species:"pig"}})
At the updateUser command, the mongod dies with:
Invalid access at address: 0 from thread: conn1 Got signal: 11 (Segmentation fault).
