From fe13b0e71752a5eb30b21e7a09d2f9370bc02387 Mon Sep 17 00:00:00 2001 From: Ben Pfaff Date: Tue, 31 Jan 2012 09:39:28 -0800 Subject: [PATCH] sflow_agent: Use snprintf() in place of sprintf(). These functions use sprintf() into a 1000-byte buffer. It appears to me that the strings they format are either short, fixed-length strings or the output of strerror(), neither of which should ordinarily overflow. However, using snprintf() cannot hurt. Launchpad bug #914160.
