Introduction
If you experience errors when using Wfuzz against SSL sites, it could be because an old know issue:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=515200
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 unexpectedlength was received.')Verifying the problem
Pycurl linked against gnutls:
$ python
>>> import pycurl
>>> pycurl.version
'libcurl/7.21.3 GnuTLS/2.8.6 zlib/1.2.3.4 libidn/1.18'Pycurl linked against openssl:
$ python
>>> import pycurl
>>> pycurl.version
'libcurl/7.21.3 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.18'Workaround
We should built pycurl against openssl:
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
