Re: How to check which version of openssl is getting compiled in into dovecot?

2017-10-27 Thread krz...@gmail.com
Never mind. It was old /lib64/libcrypto.so.1.0.0 which is dynamicly
linked when running imap-login


Re: How to check which version of openssl is getting compiled in into dovecot?

2017-10-27 Thread krz...@gmail.com
Correction. Even though i compile against fpic version of openssl
imap-login binnary is still dynamicly linked :/

root@sv1 [/usr/dovecot-2.2.33.2/libexec/dovecot]# ldd imap-login|grep ssl
libssl.so.1.0.0 => /lib64/libssl.so.1.0.0 (0x7f1428559000)

I've put new libssl.so.1.0.0 in this location from /usr/openssl-1.0.2l-fpic/lib/

# strings /lib64/libssl.so.1.0.0|grep openssl -i

SSLv3 part of OpenSSL 1.0.2l  25 May 2017
TLSv1 part of OpenSSL 1.0.2l  25 May 2017
DTLSv1 part of OpenSSL 1.0.2l  25 May 2017

looks good.

and (obviously) restarted dovecot. Outside tester
https://filippo.io/CVE-2016-2107 still says my imap on port 993 is
vournable to CVE-2016-2107. Weird.

I wish dovecot could print out version of openssl he is using on
runtime (for example to maillog, every time he starts). For example
apache can do it (and many other programs). Its a must have feature in
situation where openssl is dynamicly linked at startup (as using env
LD_LIBRARY_PATH will make it link somewhere else for example).

No, I cant because I'm compiling dovecot with openssl compiled as FPIC
which means that its not getting dynamicly linked.

When I try to compile against non-fpic openssl I just got

/usr/openssl-1.0.2l/lib/libssl.a(s23_srvr.o): relocation R_X86_64_32
against `.rodata' can not be used when making a shared object;
recompile with -fPIC

Sure, but if the OP knew this, wouldn't be asking, right?

I was kinda assuming you'd know which library it should link into. But..

$ strings /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 | grep OpenSSL
OpenSSLDie
SSLv3 part of OpenSSL 1.0.1t  3 May 2016
TLSv1 part of OpenSSL 1.0.1t  3 May 2016
DTLSv1 part of OpenSSL 1.0.1t  3 May 2016
OpenSSL 1.0.1t  3 May 2016

works at least for me. maybe this helps you?

That is not immediately helpful, though.

libssl.so.9 => /usr/local/lib/libssl.so.9 (0x28313000

You can check with ldd /usr/lib/dovecot/imap-login (or libexec)

Just check which SSL library has been linked to it.
