Bug 359955 – net-misc/openssh-5.8_p1-r1 - ssh: symbol lookup error: ssh: undefined symbol: EC_KEY_new_by_curve_name

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Lars 2011-03-22 14:54:42 UTC]

After Update to ssh-5.8_p1-r1 i couldn't connect to the server. This happens only, when source and destination Host use openssh-5.8_p1-r1




Reproducible: Always

Steps to Reproduce:
1. emerge openssh-5.8_p1-r1 and update all config and init files on all gentoo PCs
2. ssh restart on all machines
3. ssh USER@TARGET
Actual Results:  
ssh: symbol lookup error: ssh: undefined symbol: EC_KEY_new_by_curve_name

openssh uses ECDSA only if openssl provides it.  if you built against such an openssl, and then deployed against an openssl built with USE=bindist, that isnt a bug in openssh.  build against the same library you deploy against.

$ readelf -sW /usr/lib/libcrypto.so | grep EC_KEY_new_by_curve_name
  2755: 00000000000ac470    75 FUNC    GLOBAL DEFAULT   11 EC_KEY_new_by_curve_name

[Comment 2 Lars 2011-03-22 16:37:31 UTC]

Aahh...I see...

OK, recompiled openssh against openssl with use bindist

redeploy and

all is fine!


Thanks for support!
