From d27daedb6a0bf672508072100f20233d08ccf0e0 Mon Sep 17 00:00:00 2001 From: Julian Andres Klode Date: Mon, 14 Dec 2015 13:12:37 +0100 Subject: test framework: Correctly generate new paths in noopchroot The allocated buffer was one byte too small. Allocate a buffer of PATH_MAX instead and use snprintf(), as suggested by Martin Pitt. --- test/integration/framework | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) diff --git a/test/integration/framework b/test/integration/framework index 691eb793b..8ea1e1c0d 100644 --- a/test/integration/framework +++ b/test/integration/framework @@ -477,6 +477,7 @@ configdpkgnoopchroot() { #include #include #include +#include static char * chrootdir = NULL; @@ -493,13 +494,11 @@ int execvp(const char *file, char *const argv[]) { if (chrootdir == NULL || strncmp(file, "/var/lib/dpkg/", strlen("/var/lib/dpkg/")) != 0) return func_execvp(file, argv); printf("REWRITE execvp call %s into %s\n", file, chrootdir); - char newfile[strlen(chrootdir) + strlen(file)]; - strcpy(newfile, chrootdir); - strcat(newfile, file); + char newfile[PATH_MAX]; + snprintf(newfile, sizeof(newfile), "%s/%s", chrootdir, file); char const * const baseadmindir = "/var/lib/dpkg"; - char admindir[strlen(chrootdir) + strlen(baseadmindir)]; - strcpy(admindir, chrootdir); - strcat(admindir, baseadmindir); + char admindir[PATH_MAX]; + snprintf(admindir, sizeof(admindir), "%s/%s", chrootdir, baseadmindir); setenv("DPKG_ADMINDIR", admindir, 1); return func_execvp(newfile, argv); } -- cgit v1.2.3
