The discussion here describes the issue in full detail: https://forum.snapcraft.io/t/segment-fault-with-snap-store/31547
The bug was caused by a double-free in libxmlb, triggered by some specific data combination.
[Impact] This bug has been in the library since, at least, version 0.1.8, the one used in Bionic. Although the patch attached here fixes the problem in the "snap-store" snap, the bug is still present in the libraries distributed as .deb in Ubuntu, and also in the GNOME-42 extension snap. A patch has been sent both to the libxmlb repository (which has been accepted and merged) and to the Debian SALSA repository.
[Test plan] To test this bug, just download the GIT repository https://github.com/sergio-costas/test_libxmlb2 and follow the instructions. If the bug is there, valgrind will show an access to an already freed memory block and six CRITICAL errors will be shown by GLib.
[Where problems could occur] If another developer adds code that uses the 'xb_builder_xml_lang_prio_cb()' function and forgets to define a destruction function for the passed 'nodes_to_destroy' ptr_array, there would be a memory leak. |
