Title of the patch
Security update for python-httplib2
Description of the patch
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 https://github.com/httplib2/httplib2/pull/140 0.13.0 * Allow setting TLS max/min versions https://github.com/httplib2/httplib2/pull/138 0.12.3 * No changes to library.
