From 118e1ef6fabfc023126e6075f6ac0fc729cb5285 Mon Sep 17 00:00:00 2001 From: Phillip Lougher Date: Thu, 5 Mar 2009 00:31:12 +0000 Subject: Squashfs: Fix oops when reading fsfuzzer corrupted filesystems This fixes a code regression caused by the recent mainlining changes. The recent code changes call zlib_inflate repeatedly, decompressing into separate 4K buffers, this code didn't check for the possibility that zlib_inflate might ask for too many buffers when decompressing corrupted data.
