Bug#665836: openssh-server: segfault error 6 in libcrypto.so.1.0.0

[Michael Welsh Duggan <mwd@md5i.com>]

Package: openssh-server
Version: 1:5.9p1-4
Severity: important

Dear Maintainer,

When connecting to my home machine while forwarding ports, I keep getting
segfaults in sshd whenever the forwarded ports are used.  This includes
X forwarding.  The errors that appear in my syslog look like this:

Mar 26 09:11:41 maru kernel: sshd[9320]: segfault at b8749000 ip b752f678 sp bfde6de0 error 6 in libcrypto.so.1.0.0[b74c6000+1a3000]
