From eb00afb2d5bf926b08a8a9b3ca59298c2a32d8b9 Mon Sep 17 00:00:00 2001 From: Rob Landley Date: Mon, 20 Feb 2006 02:18:03 +0000 Subject: The gentoo security guys found another way to segfault busybox's decompression code: we can do a null dereference if one of our huffman tables has all zero length codes. This fixes it.
