+Subject: [PATCH] libext2fs: add sanity check to extent manipulation
+Content-Type: text/plain
+
+It is possible to have a corrupted extent tree in such a way that a leaf
+node contains zero extents in it. Currently if that happens and we try
+to traverse the tree we can end up accessing wrong data, or possibly
+even uninitialized memory. Make sure we don't do that.
+
+Additionally make sure that we have a sane number of bytes passed to
+memmove() in ext2fs_extent_delete().
+
+Note that e2fsck is currently unable to spot and fix such corruption in
+pass1.
