PyCurl SSL bug

If you experience errors when using Wfuzz against SSL sites, it could be because an old know issue:

Briefly, pycurl is built against libcurl3-gnutls, which does not work with a number of web sites. Pycurl fails with the following error message:

pycurl.error: (35, 'gnutls_handshake() failed: A TLS packet with unexpected length was received.')

Verifying the problem

  • Pycurl linked against gnutls:

    $ python
    >>> import pycurl
    >>> pycurl.version
    libcurl/7.21.3 GnuTLS/2.8.6 zlib/ libidn/1.18'
  • Pycurl linked against openssl:

    $ python
    >>> import pycurl
    >>> pycurl.version
    'libcurl/7.21.3 OpenSSL/0.9.8o zlib/ libidn/1.18'


  • We should built pycurl against openssl:

In newer Ubuntu versions, you can install libcurl in openssl or gnutls flavour:

# apt-cache search libcurl
libcurl4-gnutls-dev - development files and documentation for libcurl (GnuTLS flavour)
libcurl4-nss-dev - development files and documentation for libcurl (NSS flavour)
libcurl4-openssl-dev - development files and documentation for libcurl (OpenSSL flavour)
  • Alternatively, it can be done manually:
  1. sudo apt-get install build-essential fakeroot dpkg-dev
  2. mkdir ~/python-pycurl-openssl
  3. cd ~/python-pycurl-openssl
  4. sudo apt-get source python-pycurl
  5. sudo apt-get build-dep python-pycurl
  6. sudo apt-get install libcurl4-openssl-dev
  7. sudo dpkg-source -x pycurl_7.19.0-3build1.dsc
  8. cd pycurl-7.19.0
  9. edit debian/control file and replace all instances of “libcurl4-gnutls-dev” with “libcurl4-openssl-dev”
  10. sudo dpkg-buildpackage -rfakeroot -b
  11. sudo dpkg -i ../python-pycurl_7.19.0-3build1_i386.deb

Comment by andreas.fitzek, Sep 13, 2014 Hi,

Got it working on Ubuntu 14.04 amd64 with step 10 being: sudo PYCURL_SSL_LIBRARY=openssl dpkg-buildpackage -rfakeroot -b

Their are still some errors: ImportError?: No module named bottle

But the library is working now with openssl:

>>> import pycurl
>>> pycurl.version 'PycURL/7.19.3 libcurl/7.35.0 OpenSSL/1.0.1f zlib/1.2.8 libidn/1.28 librtmp/2.3'
