From 7c0d35a339db612aae5496424030307128f088a9 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 11 Sep 2015 13:07:36 -0700 Subject: MODSIGN: fix a compilation warning in extract-cert Fix the following warning when compiling extract-cert: scripts/extract-cert.c: In function `write_cert': scripts/extract-cert.c:89:2: warning: format not a string literal and no format arguments [-Wformat-security] ERR(!i2d_X509_bio(wb, x509), cert_dst); ^ whereby the ERR() macro is taking cert_dst as the format string. "%s" should be used as the format string as the path could contain special characters.
