When logging in via ssh with user root and password authentication I get a segfault in sshd. The problem is 100% reproduceable - I cannot login remotely at all. Any help appreciated in trying to get this addressed. This is a centos 7.3 with all the latest updates applied openssh-6.6.1p1-31.el7.x86_64 Here's a backtrace captured by running sshd under gdb. /usr/sbin/sshd -d [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1". process 14806 is executing new program: /usr/sbin/sshd Missing separate debuginfos, use: debuginfo-install keyutils-libs-1.5.8-3.el7.x86_64 nss-softokn-freebl-3.16.2.3-14.4.el7.x86_64 pcre-8.32-15.el7_2.1.x86_64 [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1".
