Fixes the following security issues: CVE-2019-14232: Denial-of-service possibility in django.utils.text.Truncator If django.utils.text.Truncator's chars() and words() methods were passed the html=True argument, they were extremely slow to evaluate certain inputs due to a catastrophic backtracking vulnerability in a regular expression. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which were thus vulnerable. The regular expressions used by Truncator have been simplified in order to avoid potential backtracking issues. As a consequence, trailing punctuation may now at times be included in the truncated output. CVE-2019-14233: Denial-of-service possibility in strip_tags() Due to the behavior of the underlying HTMLParser, django.utils.html.strip_tags() would be extremely slow to evaluate certain inputs containing large sequences of nested incomplete HTML entities. The strip_tags() method is used to implement the corresponding striptags template filter, which was thus also vulnerable. strip_tags() now avoids recursive calls to HTMLParser when progress removing tags, but necessarily incomplete HTML entities, stops being made. Remember that absolutely NO guarantee is provided about the results of strip_tags() being HTML safe. So NEVER mark safe the result of a strip_tags() call without escaping it first, for example with django.utils.html.escape(). CVE-2019-14234: SQL injection possibility in key and index lookups for JSONField/HStoreField Key and index lookups for django.contrib.postgres.fields.JSONField and key lookups for django.contrib.postgres.fields.HStoreField were subject to SQL injection, using a suitably crafted dictionary, with dictionary expansion, as the **kwargs passed to QuerySet.filter(). CVE-2019-14235: Potential memory exhaustion in django.utils.encoding.uri_to_iri() If passed certain inputs, django.utils.encoding.uri_to_iri could lead to significant memory usage due to excessive recursion when re-percent-encoding invalid UTF-8 octet sequences. uri_to_iri() now avoids recursion when re-percent-encoding invalid UTF-8 octet sequences.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
