Double free vulnerability in the init_ctx_reselect function in the SPNEGO
initiator in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5)
1.10.x through 1.12.x before 1.12.2 allows remote attackers to cause a
denial of service (memory corruption) or possibly execute arbitrary code
via network traffic that appears to come from an intended acceptor, but
specifies a security mechanism different from the one proposed by the
initiator.

Notes

Author	Note
seth-arnold	Remote unauthenticated triggering is possible though the commit message for the patch indicates why it is unlikely; thus ‘medium’.
