[patches.git] / file-4.19-init-file.patch
1 When a new struct magic_set is created as the handle to the calling application
2 (in magic_open), the "file" char * is not NULLified. This causes unexplained
3 segfaults in other apps that don't properly have their magic.mgc file created,
4 i.e. in app-arch/rpm-4.4.6-r3. The file pointer is some random value, so when
5 file_magwarn tries to report a missing magic.mgc file, for example, it tries to
6 print ms->file, which is NULL, and the segfault occurs.
