-Subject: [PATCH] decompress_gunzip: Fix DoS if gzip is corrupt
-
-On certain corrupt gzip files, huft_build will set the error bit on
-the result pointer. If afterwards abort_unzip is called huft_free
-might run into a segmentation fault or an invalid pointer to
-free(p).
-
-In order to mitigate this, we check in huft_free if the error bit
-is set and clear it before the linked list is freed.
