Description
FULL PRODUCT VERSION :
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
Latest OpenJDK 9 master affected too.
ADDITIONAL OS VERSION INFORMATION :
Linux localhost.localdomain 4.14.6-300.fc27.x86_64 #1 SMP Thu Dec 14 15:31:24 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
A DESCRIPTION OF THE PROBLEM :
When native kerberos/GSS is used (-Dsun.security.jgss.native=true) using channel binding without initAddr/acceptAddr will cause putting uninitialized "cb->initiator_address" (and potentially cb->acceptor_address too) on acceptSecContext into native kerberos library and crash of the JVM.
I was able to prepare patch for OpenJDK - see Workaround.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. use native kerberos library: -Dsun.security.jgss.native=true
2. set using ChannelBinding(byte[]) (without initAddr/acceptAddr) in gssContext
3. try to use this gssContext for negotiation
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Negotiation should be successful.
ACTUAL -
JVM will crash (because of using uninitialized cb->initiator_address) - or at least, the negotiation will fail because of wrong channel binding message checksum
