Upgrade expat copy from 2.2.0 to 2.2.1 to get fixes of multiple security
|
||
|
|
vulnerabilities including: CVE-2017-9233 (External entity infinite loop
|
||
|
|
DoS), CVE-2016-9063 (Integer overflow, re-fix), CVE-2016-0718 (Fix
|
||
|
|
regression bugs from 2.2.0's fix to CVE-2016-0718) and CVE-2012-0876
|
||
|
|
(Counter hash flooding with SipHash). Note: the CVE-2016-5300 (Use os-
|
||
|
|
specific entropy sources like getrandom) doesn't impact Python, since Python
|
||
|
|
already gets entropy from the OS to set the expat secret using
|
||
|
|
``XML_SetHashSalt()``.

Fix urllib.parse.splithost() to correctly parse fragments. For example,
|
||
|
|
``splithost('//127.0.0.1#@evil.com/')`` now correctly returns the
|
||
|
|
``127.0.0.1`` host, instead of treating ``@evil.com`` as the host in an
|
||
|
|
authentification (``login@host``).
