From mboxrd@z Thu Jan 1 00:00:00 1970 From: Baruch Siach Date: Mon, 26 Mar 2018 23:23:02 +0300 Subject: [Buildroot] [PATCH] xerces: add upstream security fix Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net CVE-2017-12627: dereference of a NULL pointer while processing the path to the DTD. xerces 3.2.1 includes this patch. But this version also added AC_RUN_IFELSE to its configure script, making cross compilation harder. Switching to cmake is also problematic since the minimum required cmake version is 3.2.0. The host dependencies check currently allows minimum cmake version 3.1.
