File 0010-Zero-fill-the-allocated-memory-for-a-new-ACE.patch of Package cifs-utils.19416
From cb3dc2fe88f6179011acbafaaed025c5bdc96131 Mon Sep 17 00:00:00 2001 From: misku <miskuu@gmail.com> Date: Wed, 31 Jul 2019 13:11:18 +0200 Subject: [PATCH] Zero fill the allocated memory for a new ACE Fixes a bug inside a call to `verify_ace_flag`. When a flag string (char*) passed as a first parameter is "0x0", the final flag value (the second parameter - the value of a pointer to uint8_t) is not modified at all and contains the original memory contents == trash. --- setcifsacl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/setcifsacl.c b/setcifsacl.c index 1b98c37..da1d742 100644 --- a/setcifsacl.c +++ b/setcifsacl.c @@ -672,7 +672,7 @@ build_cmdline_aces(char **arrptr, int numcaces) goto build_cmdline_aces_ret; } - cacesptr[i] = malloc(sizeof(struct cifs_ace)); + cacesptr[i] = calloc(1, sizeof(struct cifs_ace)); if (!cacesptr[i]) { printf("%s: ACE alloc error %d\n", __func__, errno); goto build_cmdline_aces_ret; -- 2.16.4
