Fix axis traversal from attribute and namespace nodes When traversing the "preceding" axis from an attribute node, we must first go up to the attribute's containing element. Otherwise, text children of other attributes could be returned. This made it possible to hit a code path in xmlXPathNextAncestor which contained another bug: The attribute node was initialized with the context node instead of the current node. Normally, this code path is only hit via xmlXPathNextAncestorOrSelf in which case the current and context node are the same. The combination of the two bugs could result in an infinite loop, found with libFuzzer. Traversing the "following" and the "preceding" axis from namespace nodes should be handled similarly. This wasn't supported at all previously.

XML toolkit from the GNOME project Full documentation is available on-line at http://xmlsoft.org/ This code is released under the MIT Licence see the Copyright file. To build on an Unixised setup: ./configure ; make ; make install To build on Windows: see instructions on win32/Readme.txt To assert build quality: on an Unixised setup: run make tests otherwise: There is 3 standalone tools runtest.c runsuite.c testapi.c, which should compile as part of the build or as any application would. Launch them from this directory to get results, runtest checks the proper functionning of libxml2 main APIs while testapi does a full coverage check. Report failures to the list. To report bugs, follow the instructions at: http://xmlsoft.org/bugs.html A mailing-list xml@gnome.org is available, to subscribe: http://mail.gnome.org/mailman/listinfo/xml The list archive is at: http://mail.gnome.org/archives/xml/ All technical answers asked privately will be automatically answered on the list and archived for public access unless privacy is explicitly required and justified.
