When I last researched this when the first problem with that function
was announced, no other functions inside OpenSSL called it.  That
still appears to be the case:

/usr/src/crypto/openssl> grep -R SSL_get_shared_ciphers .
./apps/s_client.c:              p=SSL_get_shared_ciphers(s,buf,sizeof buf);
./apps/s_server.c:      if (SSL_get_shared_ciphers(con,buf,sizeof buf) != NULL)
./apps/s_server.c:                      p=SSL_get_shared_ciphers(con,buf,bufsize);
./doc/ssleay.txt:SSL_get_shared_ciphers
./doc/ssl/ssl.pod:=item char *B<SSL_get_shared_ciphers>(SSL *ssl, char *buf, int len);
./ssl/ssl.h:char *      SSL_get_shared_ciphers(SSL *s, char *buf, int len);
./ssl/ssl_lib.c:char *SSL_get_shared_ciphers(SSL *s,char *buf,int len)
./util/ssleay.num:SSL_get_shared_ciphers                  65    EXIST::FUNCTION:

Also, sendmail does not use it.
