From 2ec49059fbb09a119ede30da946b46e98c58199c Mon Sep 17 00:00:00 2001 From: Simon Tatham Date: Mon, 22 Sep 2014 10:28:05 +0100 Subject: [PATCH] SECURITY: fixed fix to buffer handling The implementation of buf_remaining_space in 92795040 was entirely broken. It failed to take buf->size into account at all !
