From b4faea50c35d92a67d1369355b49cc3efba78406 Mon Sep 17 00:00:00 2001 From: Rich Salz Date: Fri, 1 May 2015 23:10:31 -0400 Subject: Use safer sizeof variant in malloc For a local variable: TYPE *p; Allocations like this are "risky": p = OPENSSL_malloc(sizeof(TYPE)); if the type of p changes, and the malloc call isn't updated, you could get memory corruption. Instead do this: p = OPENSSL_malloc(sizeof(*p)); Also fixed a few memset() calls that I noticed while doing this.
