From 59053968e756e9063c512fba59717c32621e3f1a Mon Sep 17 00:00:00 2001 From: Pavel Kopyl Date: Fri, 3 Nov 2017 22:18:35 +0300 Subject: [PATCH] do_body: fix heap-use-after-free. The memory pointed to by the 'push' is freed by the X509_NAME_ENTRY_free() in do_body(). The second time it is referenced to (indirectly) in certify_cert:X509_REQ_free().
