Description Andrej Nemec 2016-12-09 12:09:05 UTC

An error within the "tar_directory_for_file()" function (gsf-infile-tar.c) in GNOME Structured File Library before 1.14.41 can be exploited to trigger a Null pointer dereference and subsequently cause a crash via a crafted TAR file.

Upstream patch:

https://github.com/GNOME/libgsf/commit/95a8351a75758cf10b3bf6abae0b6b461f90d9e5
