Release 2.4.1 Sun May 23 2021
Bug fixes:
#488 #490 Autotools: Fix installed header expat_config.h for multilib
systems; regression introduced in 2.4.0 by pull request #486
Other changes:
#491 #492 Version info bumped from 9:0:8 to 9:1:8;
see https://verbump.de/ for what these numbers do
Release 2.4.0 Sun May 23 2021
Security fixes:
#34 #466 #484 CVE-2013-0340/CWE-776 -- Protect against billion laughs attacks
(denial-of-service; flavors targeting CPU time or RAM or both,
leveraging general entities or parameter entities or both)
by tracking and limiting the input amplification factor
(<amplification> := (<direct> + <indirect>) / <direct>).
By conservative default, amplification up to a factor of 100.0
is tolerated and rejection only starts after 8 MiB of output bytes
(=<direct> + <indirect>) have been processed.
The fix adds the following to the API:
- A new error code XML_ERROR_AMPLIFICATION_LIMIT_BREACH to
signals this specific condition.
- Two new API functions ..
- XML_SetBillionLaughsAttackProtectionMaximumAmplification and
- XML_SetBillionLaughsAttackProtectionActivationThreshold
.. to further tighten billion laughs protection parameters
when desired. Please see file "doc/reference.html" for details.
If you ever need to increase the defaults for non-attack XML
payload, please file a bug report with libexpat.
- Two new XML_FEATURE_* constants ..
- that can be queried using the XML_GetFeatureList function, and
- that are shown in "xmlwf -v" output.
- Two new environment variable switches ..
- EXPAT_ACCOUNTING_DEBUG=(0|1|2|3) and
- EXPAT_ENTITY_DEBUG=(0|1)
.. for runtime debugging of accounting and entity processing.
Specific behavior of these values may change in the future.
- Two new command line arguments "-a FACTOR" and "-b BYTES"
for xmlwf to further tighten billion laughs protection
parameters when desired.
If you ever need to increase the defaults for non-attack XML
payload, please file a bug report with libexpat.
Bug fixes:
#332 #470 For (non-default) compilation with -DEXPAT_MIN_SIZE=ON (CMake)
or CPPFLAGS=-DXML_MIN_SIZE (GNU Autotools): Fix segfault
for UTF-16 payloads containing CDATA sections.
#485 #486 Autotools: Fix generated CMake files for non-64bit and
non-Linux platforms (e.g. macOS and MinGW in particular)
that were introduced with release 2.3.0
Other changes:
#468 #469 xmlwf: Improve help output and the xmlwf man page
#463 xmlwf: Improve maintainability through some refactoring
#477 xmlwf: Fix man page DocBook validity
#458 #459 CMake: Support absolute paths for both CMAKE_INSTALL_LIBDIR
and CMAKE_INSTALL_INCLUDEDIR
#471 #481 CMake: Add support for standard variable BUILD_SHARED_LIBS
#457 Unexpose symbol _INTERNAL_trim_to_complete_utf8_characters
#467 Resolve macro HAVE_EXPAT_CONFIG_H
#472 Delete unused legacy helper file "conftools/PrintPath"
#473 #483 Improve attribution
#464 #465 #477 doc/reference.html: Fix XHTML validity
#475 #478 doc/reference.html: Replace the 90s look by OK.css
#479 Version info bumped from 8:0:7 to 9:0:8
due to addition of new symbols and error codes;
see https://verbump.de/ for what these numbers do
Infrastructure:
#456 CI: Enable periodic runs
#457 CI: Start covering the list of exported symbols
#474 CI: Isolate coverage task
#476 #482 CI: Adapt to breaking changes in image "ubuntu-18.04"
#477 CI: Cover well-formedness and DocBook/XHTML validity
of doc/reference.html and doc/xmlwf.xml |
