[Security] Bump jinja2 from 2.10.1 to 2.11.3

[dependabot-preview]

Bumps jinja2 from 2.10.1 to 2.11.3. This update includes a security fix.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Regular Expression Denial of Service (ReDoS) This affects the package jinja2 from 0.0.0 and before 2.11.3. The ReDOS vulnerability of the regex is mainly due to the sub-pattern [a-zA-Z0-9.-]+.[a-zA-Z0-9.-]+ This issue can be mitigated by Markdown to format user content instead of the urlize filter, or by implementing request timeouts and limiting process memory.

Affected versions: < 2.11.3

Release notes

Sourced from jinja2's releases.

2.11.3

This contains a fix for a speed issue with the urlize filter. urlize is likely to be called on untrusted user input. For certain inputs some of the regular expressions used to parse the text could take a very long time due to backtracking. As part of the fix, the email matching became slightly stricter. The various speedups apply to urlize in general, not just the specific input cases.

Version 2.11.3

Released 2021-01-31

• Improve the speed of the urlize filter by reducing regex backtracking. Email matching requires a word character at the start of the domain part, and only word characters in the TLD. 1343

Version 2.11.2

Released 2020-04-13

• Fix a bug that caused callable objects with __getattr__, like ~unittest.mock.Mock to be treated as a contextfunction. 1145
• Update wordcount filter to trigger Undefined methods by wrapping the input in soft_str. 1160
• Fix a hang when displaying tracebacks on Python 32-bit. 1162
• Showing an undefined error for an object that raises AttributeError on access doesn't cause a recursion error. 1177
• Revert changes to ~loaders.PackageLoader from 2.10 which removed the dependency on setuptools and pkg_resources, and added limited support for namespace packages. The changes caused issues when using Pytest. Due to the difficulty in supporting Python 2 and 451 simultaneously, the changes are reverted until 3.0. 1182
• Fix line numbers in error messages when newlines are stripped. 1178
• The special namespace() assignment object in templates works in async environments. 1180
• Fix whitespace being removed before tags in the middle of lines when lstrip_blocks is enabled. 1138
• ~nativetypes.NativeEnvironment doesn't evaluate intermediate strings during rendering. This prevents early evaluation which could change the value of an expression. 1186

Version 2.11.1

Released 2020-01-30

• Fix a bug that prevented looking up a key after an attribute ({{ data.items[1:] }}) in an async template. 1141

Version 2.11.0

Released 2020-01-27

• Drop support for Python 2.6, 3.3, and 3.4. This will be the last version to support Python 2.7 and 3.5.
• Added a new ChainableUndefined class to support getitem and getattr on an undefined object. 977
• Allow {%+ syntax (with NOP behavior) when lstrip_blocks is disabled. 748
• Added a default parameter for the map filter. 557
• Exclude environment globals from meta.find_undeclared_variables. 931
• Float literals can be written with scientific notation, like 2.56e-3. 912, 922
• Int and float literals can be written with the '_' separator for legibility, like 12_345. 923
• Fix a bug causing deadlocks in LRUCache.setdefault. 1000
• The trim filter takes an optional string of characters to trim. 828
• A new jinja2.ext.debug extension adds a {% debug %} tag to quickly dump the current context and available filters and tests. 174, 798, 983
• Lexing templates with large amounts of whitespace is much faster. 857, 858
• Parentheses around comparisons are preserved, so {{ 2 * (3 < 5) }} outputs "2" instead of "False". 755, 938
• Add new boolean, false, true, integer and float tests. 824
• The environment's finalize function is only applied to the output of expressions (constant or not), not static template data. 63
• When providing multiple paths to FileSystemLoader, a template can have the same name as a directory. 821
• Always return Undefined when omitting the else clause in a {{ 'foo' if bar }} expression, regardless of the environment's undefined class. Omitting the else clause is a valid shortcut and should not raise an error when using StrictUndefined. 710, 1079
