This update for python-httplib2 contains the following fixes: security fixes included in this update: - cve-2021-21240: fixed a regular expression denial of service via malicious header (bsc#1182053).
- cve-2020-11078: fixed an issue where an attacker could change request headers and body (bsc#1171998).
non-security fixes included in this update: - update in sle to 0.19.0 (bsc#1182053, cve-2021-21240) - update to 0.19.0: * auth: parse headers using pyparsing instead of regexp * auth: wsse token needs to be string not bytes - update to 0.18.1: (bsc#1171998, cve-2020-11078) * explicit build-backend workaround for pip build isolation bug * important security vulnerability cwe-93 crlf injection force %xx quote of space, cr, lf characters in uri.
* ship test suite in source dist - update to 0.17.3: * bugfixes - update to 0.17.1 * python3: no_proxy was not checked with https * feature: http().redirect_codes set, works after follow(_all)_redirects check this allows one line workaround for old gcloud library that uses 308 response without redirect semantics.
* important cache invalidation change, fix 307 keep method, add 308 redirects * proxy: username/password as str compatible with pysocks * python2: regression in connect() error handling * add support for password protected certificate files * feature: http.close() to clean persistent connections and sensitive data - update to 0.14.0: * python3: proxy_type_socks5 with str user/pass raised typeerror - version update to 0.13.1 0.13.1 * python3: use no_proxy 0.13.0 * allow setting tls max/min versions 0.12.3 * no changes to library.
Distribute py3 wheels.
0.12.1 * catch socket timeouts and clear dead connection * officially support python 3.7 (package metadata) 0.12.0 * drop support for python 3.3 * ca_certs from environment httplib2_ca_certs or certifi * proxy_type_http with non-empty user/pass raised typeerror: bytes required * revert http:443->https workaround * eliminate connection pool read race * cache: stronger safename 0.11.3 * no changes, just reupload of 0.11.2 after fixing automatic release conditions in travis.
0.11.2 * proxy: py3 nameerror basestring 0.11.1 * fix http(s)connectionwithtimeout attributeerror proxy_info 0.11.0 * add digicert global root g2 serial 033af1e6a711a9a0bb2864b11d09fae5 * python3 proxy support * if no_proxy environment value ends with comma then proxy is not used * fix unicodedecodeerror using socks5 proxy * respect no_proxy env var in proxy_info_from_url * no_proxy=bar was matching foobar (suffix without dot delimiter) new behavior matches curl/wget: - no_proxy=foo.bar will only skip proxy for exact hostname match - no_proxy=.wild.card will skip proxy for any.subdomains.wild.card * bugfix for content-encoding: deflate - deleted patches httplib2 started to use certifi and this is already bent to use system certificate bundle.
- handle the case when validation is disabled correctly.
The 'check_hostname' context attribute has to be set first, othewise a "valueerror: cannot set verify_mode to cert_none when check_hostname is enabled."
Exception is raised.
- handle the case with ssl_version being none correctly - use ssl.create_default_context in the python2 case so that the system wide certificates are loaded as trusted again.
- source url must be https.
- spec file cleanups - update to 0.10.3 * fix certificate validation on python less than equal 2.7.8 without ssl.
Certificateerror - update to 0.10.2 * just a reupload of 0.10.1, which was broken for python3 because wheel distribution doesn't play well with our 2/3 split code base.
* fix socket error handling - remove httplib2-bnc-818100.patch, merged upstream.

Successful exploitation allows attacker to compromise the system.
